You're not wrong. The other perk of 39s though is that there's a good sized part of the community that cares about winning over dmg charts. And skill matters a bit more: if you're a complete noob warlock or hunter, a skilled player of a different class has a chance against you. And the rogues that are really unfun to play against are the pro players. I pwn noob rogues on my priest when I spec shadow.
Also, 39 3v3 arenas are the best. So fun.
