4v4 is actually good fun and smart idea!
Only ArmsWarriors / Elementals crying about 4v4, you know why? Because they will no longer faceroll their way to 2300+ in 3v3 soloQ
When was the last time you saw a Boomy / Feral / Rogue or anything that is not Ele / Warr in soloQ?
SoloQ as 3v3 was never balanced, if you ever played 3v3 soloQ you would know anything above 1800 rating is Thundercleave ONLY.
SoloQ 4v4 is actually a smart idea.
4v4 allows for way more diversity in comps, and queues are overall much shorter because there is no restrictions.
If you like 3v3 then make a team and queu 3v3.
Stop cry.
