Hey Fluffy- the tone is shifting here a bit, but I want to be clear on why. The problem you had with my grievance is that you cannot manage to do so many things at the same time. Additionally, the piece that I pointed out to you- regarding prose, grammar, and character believability, are the cornerstone of great roleplay. Command is supposed to be not only an example of individuals capable of doing mechanics of a role, but doing them in a manner that is a) compliant with the ruleset b) encourages the round and flow c) with a developed character and most importantly d) doing so through roleplay, of which quality is ideally above par comparatively to the playerbase. That being said, there are many characters who are NOT command and roleplay AMAZINGLY, and conversely there are some in Command who neglect occasionally proper roleplay standards.
You posted a huge list. Below I have grouped them into categories. I believe that almost the entirety (except one) are 100% completely expected of someone who is both roleplaying well and running Command. It often times that a trial whitelistee is someone who roleplays well, or can do the role of Command well, but must be taught to do both at the same time. I fear that through your trial you've demonstrated that both these skillsets (roleplaying well and the command role separately) need some work.
Anyway the list you posted above stating you can't do them all are categorized neatly into some broad subjects that are essential to good Command RP:
Departmental Orchestration & Running of Security (Heightened Responsibilities of Command & Difficulty Rating of Head of Security (difficulty is listed as one of the hardest in game))
Send personalized instructions on what to for every change of the situation
Send status updates along with the above
Get status updates from everyone on how are things going
Go around checking how things are going in the ship
Observe the brig to ensure the correct sentence and proceeding is applied
Check the IC law on the wiki to make sure of the above (You should, without a doubt, be able to have a decent knowledge of IC regulations as a member of Command, doubly so as a HoS. Many HoS can quote i-codes. This is just being familiar with IC regs which is expected as HoS)
Remind everyone that we have investigators and to hand over the antags for the processing, to the investigators to go check things reported by the crew, to officers to go check potential calls (Simple departmental orchestration, making sure people stay in their lanes)
Read the security history of the multiple POIs that the investigators print and assemble, which do not print the charges so you have to use the PDA (Not really needed, you can just stay informed through talking to your detectives and having roleplay conversations about people they've found interesting.)
Try to negotiate with the antags (Through Roleplay)
See when it's time to send bystanders away in a manner that makes sense for the IC reason to protect them without cutting the OOC fun of seeing the gimmick (Aka roleplay)
Act in a Chain of Command (Heightened Responsibilities of Command)
Send status updates along with the above
keep the captain and rest of the command updated, which is basically doing the same thing as above but in another channel
Check the bridge and bridge crewmen to know and remain updated on the status of third party ships, including roleplaying with them (Not always essential as HoS, but if you're the only Command, yes this is of course a requirement of being in Command)
Try to negotiate with the antags
Roleplay Capability (Expected of all Characters, Not just Command)
Go outside the department to meet and talk with various characters (not just doing your mechanic role of say just doing surgery quietly)
writing and doing actions with the Me command
Evaluate how the character would IC react to something
Evaluate how OC is best for the round to react to something
Merge the two together in a balanced way
Get to know new characters
Coordinate with other departments to prepare for medical emergencies, breaches, explosions, scientifical analysis and whatnot that makes IC sense (Otherwise known as 'responding to what's going on in round and roleplaying')
Read through all the local chat, public channels and our channel to see if there's an emergency, someone asked something to me while i was writing or doing something, if I'm needed somewhere, if there's something I should be aware about (Keeping up with the flow of text is expected of someone in Command. Like I mentioned, I waited about 20 seconds for you to shake my RPC's hand, and I did not see a typing indicator for your character. Unless you had this disabled I'm not certain what you were doing.)
Feign ignorance on what is happening when comms do not work, the antag starts sucking blood, morph into some mass or whatnot, in a believable way (This is a simple concept known as 'preserving round integrity' and should be done to an extent)
Talk about it with the people present
Have a Developed Character
Characterize the character with more distinctive quirks (this is just developing a character and roleplay vs. creating a 'John Doe' to play a role)
Go outside the department to meet and talk with various characters
Maintain and foster established knownship/friendship with other characters (Known as having character relations, something that is a must)
recall what each said or did, what we were discussing, what was the last thing we talked about, evaluate what's appropriate for the round to talk about (Otherwise known as 'Know whats going on')
Get to know new characters (And form relationships with them if you find them interesting? God forbid)
Not Always your Responsibility as HoS
Coordinate with the other departments to involve them as possible in the gimmick - This majority of the antagonists responsibility
Things You should actually probably not be doing unless necessary:
Go hunt the antags with the rest of the security myself as possible (You should definitely be on-scene, but spearheading major things when you have appropriate staff is not something the HoS should do so directly, and is called 'frontlining'. Further, doing so without like, putting on a bulletproof vest, is also seen as a faux-pas.)
Additional remarks: An ancedote regarding a gruff HoS doing the bare minimum to keep the department running is not something I want to see be an excuse for lack of good RP. They may have been a trial whitelistee, they may be under investigation for HoS removal, they may have had a player complaint immediately after the round for failing to RP well.
