To give you some context to how hilairious League of Legends play can be, and how the whiner's do similar things, I'll give you an example of how people explain imbalance.
New character comes out named Zyra, everybody complains when matched against her, she's too strong and needs to be cuddled into the ground.
New character comes out named Diana, everybody complains when matched against her, needs cuddles blah blah blah
Older champions fair well against the two new ones, people who use Zyra and Diana complain that they're underpowered and champions X(who beat that champ) needs Cuddling, after being in the game for about 2 years.
Just something to ponder before whining Imba on the forums!
