Yes other admins can remove you if you promote them, so be careful and only promote loyal trustworthy people. The system of troop leadership is pretty weird in this game tbh, there needs to be a rank above and beyond admin that has authority over other admins, but that is not so.
In the second troop I was in there was essentially a coup and one of the admins who was a big spender removed everyone who didn't spend a lot, including the original creator of the troop, renamed the troop and basically took it for his own.
I agree with the rank above admin is required, but I can also see the logic behind not having it. I have seen in many games where there is a good active troop, but the troop leader goes inactive and the troop then goes to shit.
Having it this way would probably be a way to get around that obsticle, although I think a better way would be to have "4 Senior admin slots" which can:
1.) give and remove admin access.
2.) Kick people from troop
4.) Add people from troop
5.) change troop info
Then the admin level below it which can just
1.) Add people to troop
2.) Invite to troop
3.) Change troop info
but developing something like that comes at the expense of developing something else. atm there are 100's of troops and it seems that it works most of the time, so its probably best if penny puts effort into developing something else, like an android version.
I know I know ;) but starting raids was one of the major reasons why we put some people admin. At least, when we were still small. Now there's a lot more work. But guess they have other priorities now (android, then FB, ... ).
Maybe we could work together on a clean layout for this?
