Guild Wars 2

TL;DR: Remove AoE cap?
Or do you mean something else?

This is a poor idea.

What constitutes a blob? 5 people? 20 people? 40 people? 70 people? The terms blob, zerg, raid and countless other synonyms used by people have no pre-defined values. Deciding on this number isn’t easy and isn’t hard to control.

Then there’s the grief aspect to it. What happens if you are 19 guys in a group and a random PUG comes up and starts hanging out giving you a debuff? Do you have any kind of recourse to solve that? What if a whole group comes over?

If they want to discourage blobbing, they need to do so through smart game play design decisions. The recent stability nerf was poorly thought out and implemented because all it has done is encouraged ranged blobbing far worse than we’ve seen since the start of the game. Decisions like this can’t be implemented without thinking them through fully.
