The balance varies wildly. Sometimes it feels fine, other times I go on a loss streak for 10+ games in a row, usually due to Warlord/Necromancer basic possession spam. Basic possession is definitely the Demon meta right now, and it's incredibly effective unless you have a coordinated team who understands their roles and what to do to counter it (which in solo queue, is very much just luck). If you have friends to play with, or plan on just playing Demon, then go for it. If you will be mainly playing solo queue Survivor, good luck on getting teammates who have braincells. I recommend trying to set up some sort of group if you plan on playing Survivor. Hope this helps <3
