However they decide to balance these characters, I just really hope they get it done ASAP. Ideally, this should be in a day one patch. I dread the thought of having to wait several weeks to get this sorted out. Getting used to one thing, and then having to readjust can be pretty annoying. And on top of that, it kind of brings up a sort of "moral" dilemma. Do I avoid Rose because she's purportedly OP to the point of being unfair? Or do I pick her every single time, because otherwise I'm pretty much handicapping myself, and that hurts not only myself, but my teammates?
Keep in mind how confusing and potentially frustrating major balance changes can be for new/casual players. One day they're finally starting to get the hang of things, and their confidence starts to rise, and then all of a sudden they're struggling to get any kills. A lot of those players may not understand what happened and get discouraged. I mean, it's not their fault that a particular character was OP.
At this point it's pretty clear something needs to be done about both the Imp and Rose. The only question is exactly how to handle it. The consensus for the Imp seems to be that he should fall between his iteration in the beta and where he is now. The solution for Rose seems to be a bit more debatable, with some people wanting her nerfed back to her beta iteration, and some wanting her to keep some sort of buffs. Personally I'm part of the latter group. Perhaps giving her a slight damage buff as a previous poster suggested (0.5 - 1 instead of 1.5) would be sufficient.
I hope this gets sorted out very quickly, because I want everyone to have a good experience as possible so we have a large community as possible. I haven't even played the final game yet, but just reading all the posts about this on here and the Reddit forums has me kind of depressed.
