Im actually enjoying season 6 quite a bit, ward properly, react properly.
Riots design philosophy is beginning to stick out to many players and we are taking advantage of it.
Grab some friends and enter queue as a 5 man, then you'll literally see what you are doing wrong that frustrates you.
Everything is balancing out (albeit very slowly) and come summer, it will be stronger and the lower levels may even begin to understand how to play the new format of gameplay that league is supplying to us this season
If you dont like death timers, play safe dont die.
If you are getting split pushed often, pay attention to the map a d ward.
If you feel underpowered, play safe, and dont roam alone (this includes pushing minions passed a downed tower of yours)
This game is finally starting to introduce skill being a factor of gameplay again, its just up to you to realize where and when to use it.
Dont overcommit.
