I like the idea of new skins for donators, but I don't like the idea of a new team for them only.
Not only would such a team be exclusionary, but it would limit the ability of staff members such as myself whom are not donators, to read the team chat of suspected cheaters on the donator team.
If it can be done, a 2nd or 3rd skin could be assigned to each team, but only donators would be able spawn with them. However, careful consideration should be payed to the spawn weapons of those skins, in order not to upset the balance that was worked in to the current set up.
ps. I think there should be some more teams created for everyone to use, so that we can have conflict zones in other areas of the map brought about by relative proximities
of the new teams to the existing ones.
