I play a scrapper, and had the good luck to be invited into a 4 scrapper team once. Everyone had to carry a few awakens, but it changed gameplay completely.
Ever since then whenever I join a team I let the Def/Cons know I fully expect to eat some floor, and will not repay a rez with the gracious refrain "Where the F was my heal !!?"
This usually gets a "lol - I hate that" and a few friendly pointers about whether they have AoE or targeted heals, etc... Much better to find that out before I'm face down.
Point is: you've paid $15 to play with other people. Teams are the most fun if you talk to them.
