I think we should go back to season 5 when the game was actually fun XD

This season the game has been so orientated on laning phase and playing champs that does a better job. For example why pick voli when you can play Cho'gath I aint saying voli is worse off just giving a random example. My point is that the game was initially designed for a team based game, but recently the game doesn't feel like it does that anymore. If I am wrong then correct me but I have moved from silver 5 and reaching plat 5 yesterday :p this season and just haven't seen so much teamwork like the old days. Not sure how it could be done but I thought it should be something for the public to discuss xD. Gl and HF
