Unless you play a tank class (primarily war) or a healer (disc/resto druid), you won't have any fun.
As much as I like pvp, I've completely given up on taking my 44- or so rogue through bgs. The pain and frustration caused is simply not worth it.
I survive two hits from prot wars. My opener? Yeah, they just shrug it off.
I can't do shit against disc priests and by attacking them, you'll just be another honorable kill. Resto druids (and balance)? Travel form out, heal up, gg.
It's nice to blizz trying to fix things, with scaling and nerfing shield slam, but it's far from enough, and until more is done, I'll bore myself with... uhg.. pve.
aka I won't have many 90s.
