Premades should get a potency reduction per player in frontlines

[Xylira]

This does absolutely nothing against the tryhards, or did you forget about the battle high progression adjustment? Even if you made them weak, you will still lose to the 4 mans while they're down 20% of their stats.
What you will do is punish the casual premades, you know, those that only play for half an hour or those that decides to do the roulette as a group before leaving for the day?

Someone's going to suffer one way or another. Do nothing and the tryhard premades make things unenjoyable for everyone else. Penalize/remove premades entirely and the more casual group queuers suffer.

The only feasible middle ground I can even think of would be for SE to conditionally penalize tryhard premades. Maybe some kind of MMR ranking system for frontlines, but only kicks in a penalty if two or more high ranking players are in a premade, scaling up the more/higher they are. If you're a regular casual player pvping with friends that don't all have highly skewed win rates or whatnot, it wouldn't impact you.
