Good or Bad? I think both.....

I firmly believe they want to get rid of 2v2 even tho it is the most accessible bracket. There has been talk about other types of brackets and I can only see 4v4. 5s is difficult logistically as it is so I dont see anything above 5v5. 4v4 might be hard to balance also but might be easier than 2s. 2 healer/2dps or 3dps/1healer are really your only comps and maybe 4dps as gimmick comp.

4s might end up being worse than 2s to balance overall but I really see them killing 2s in the near future. For me personally, 3s is my favorite so I am fine with no changes. Although, I wouldnt mind seeing 4v4 as I could just add a healer and go 3dps/1 healer. /shrug
