@Riot, do something about twitch and kog'maw, they really can't survive without their supports.
Of course, when support and other team members perform well, they can still do well. However, when they don't peel you at all, it would be really easy for bruisers to kill you.
They just flank you and you die and will not be able to deal any dmg. You are either forced out of position to deal completely no damage or just die.
An option would be fix them so they will be the exact the same as Lucian/Caitlyn, self-peel and strong lane phase.
Riot plz, or delete all those bruisers.
