Autoreroll is very hostile design choice, intention of which i assume is of streamlining gameplay and provide more opportunities for comeback, but in practise just ruining expiriance for both teams benefiting noone.
Talking abaut comeback, game already has fine mecanic of reducing reroll time upon deth and it's does it's job, in my expiriance comeback happens often enough, also sometimes u just lose and it's fine, game time much shorter that makes it a lot less painfull. But autoreroll doesn't helps here, in fact it actively pushing loosing team in half of a situations. For example u rolled a nice build that requires some items and other team has early game stuff that kills u a lot, well u ♥♥♥♥♥♥ then, game said it's time to make ur build worse.
In practice it's just mean that u have 3 normal ability slots and one ♥♥♥♥♥♥♥♥ slot in which u better not roll something good, or u be punished for that. That is no fun.
As i whine about it in chat, i only got responses agreeing with me, so i can assume that many people don't like this change either.
I'm don't really see a problem that get solved by this change, but only way to restrict player's options and harm overall experience. Please change it or scrap it
