Heavy Getting My Ass Kicked Recently

Just my opinion of course...

Played heavy since launch, haven't picked another class ever. I don't know what's changed but I was pretty decent at this game, until new weapons and patches. I'm getting my ass kicked, everyone playing lights buzzing round like bees, it's frustrating. I'm gonna join the party, apparently I didn't get the memo.

Doesn't matter what weapon I use, if my team ain't sticking next to me, I'm dead in 2 seconds, entire teams of 3 just blasting through me. I've realised that heavy is pretty useless without a strong team these days.
