Forced Department Heads

[Avack]

I should say I'm not fond of anything that involves forcing people into roles. However, I think this one could be alright, just because heads are basically just regular people in their department with a bit more access. I do have some issues with it as presented, though:

• I don't think this should bypass having roles set to unwanted. If somebody doesn't want the stress/responsibility of a head role or wants to avoid them for another reason, they should have the option to do so by setting them to unwanted.
  
• The HoP should not be forced. They are, in my opinion, the least important head and the one with the least connection to the roles of their department. It's true that they're theoretically in charge, but in the context of 2 all that happens is they change IDs until they get completely forgotten. If HoP is forced, people will be redirected to it from productive and useful head roles and either achieve nothing or just do the job they wanted anyway.
  
• The HoS should respect the whitelist, IMO, but that's a rant for another time.
  

Probably worth noting at this point that captain and AI are already forced but respect unwanted prefs, which I think is good and fine.
