Guild Wars 2

I don’t know if anyone has discussed or noticed this before, but as someone who primarily roams/scouts I’ve noticed the following;
Hylek are the only mercenaries that will repeatedly attack a camp until they’re neutralized. Dredge will attack a few times and Ogres only once. What’s up with this? I do a lot of WvW and I’ve been aware of this for quite some time, but it has only recently been bothering me. Does anyone know the reason for this? And if not, it would be great if the merc camps could get a bit of dev attention. As is, Hylek are the only valuable mercs to have, Ogres will basically come and attempt to flip the camp, fail and never come back. Dredge are kind of middle ground, although they succeed at killing all the NPC’s quite often because of how tanky they are.

Maybe that’s because of the color-strength balance?

Hyleks are between strongest and middle server
Dredge are between strongest and weakest server
Ogres are between middle and weakest server

The stronger a server the more he is bothered by stronger mercs.
