Problem is not that T4 is too difficult .. problem is, that when you become T4 and try to get better, "real" T4 players will kick you because you are not good enough. they blame you because they lose the game and due to that they lose ELO.
They even remember your name if you maybe had a really bad day so they kick you just the second you join.
I personaly blame ELO for it, people are too focused on it.
people dont try to make their best game anymore, they just wanna win games or better to say dont lose games!
so this is why many people ("ELO-watchers") leave the game before it ends (and they would lose then) so there is no ELO loss.
but i think you all know this, dont have to tell you.
since i signed up PRO this problem became even worse!!!
in fact i am a bit anxious before joining a game because i dont want to be THE reason why my team doesnt win.
unfortunately this is the reason why i wont sign up PRO again.
