In 3v3 it mostly about what cham you use that allow you to win.If you have a team with like ad carrry or melee cham like jax and tryn you already have about 70 percent of winning.and it so easy to come back in 3v3 cause u can easily tank the tower and win.But 3v3 is good cause the match is not that long and if you want to play with a few friends.

K i dont really see a reason that you are stating there is no balance in 3's I agree it needs more balance but you should at least know why. The jungle is probably the biggest reason to balance TT its not updated like SR so its a lot more unforgiving as well as farther apart than SR jungle making some champs impossible to jung with a high chance of success. Also the distance to your tower in 3's is far so if you get caught early game you can be totally screwed.

3v3 is not the map for jungler. but u can still get those buff on the top. But i dont see y the jungle is that big a deal.

I play 3v3 because it a fast game and dont get much lag.
