Well, i think a map poll like in siege, battle etc. won´t be implemented since people would always poll for the same map.
The switch to a random map sounds good, even though there has to be implemented a kind of a cooldown for it because otherwise, people will poll until they get the map they want.
Defend the Virgin:
Make it possible to text to anyone even when you're dead, mainly because NPC's are stuck or hidden somewhere, and the players cant find them.
I´m uncertain about this. Usually this is a feature to prevent the specs to reveal the enemy movements to your team, but in DTV, there are obviously no "secret" tactics of the attackers. Therefore, I´d agree, but on the other hand, it would lead to the situation that nobody has to stay at the virgin to prevent her from getting harmed/ informing his team about enemies attacking the virgin.
I know, the same effect can be achieved through communication via teamspeak, but this acutally enforces teamplay by itself.
