I'm also using brute to attack the enemy base. It's more of a tank than the other attackers. He can take more damage, and has the disconade which I usually throw when I've attracted enough enemies).
If you think the Devastator is OP (/too powerful), take in consideration that it has a very long reload time compared to other fusors. And a miss is more costly than usual too. One can't argue that if a person is skilled enough to always have the upper hand (being able to direct hit most of the time) with the Devastator, it's too powerful. Because then it's the skill of the player that makes it so good. Oh - and it deals 1204 on direct hit, FYI.
On a side note (well, this is just T:A general thread anyway):
