Is this the PvP whine forum?

Discussions of class balance are perfectly appropriate here. Discussions of BG or Arena map design, how MMR is calculated, or less class-based discussions are better suited for the PvP forum.

However, you should know as a general rule of thumb that a thread that contains little actual information is one that the developers are likely to skim through or ultimately skip over.

"LOL Rogues are OP," (perhaps with a link to a screenshot of questionable authenticity) might make you feel better, but won't do much towards actually influencing our decision to change the game unless you add why or under what circumstances you think that's the case. :)
