Guild Wars 2

EDIT2: IGNORE THIS THREAD. It seems the OP has retracted his original post and made my post seem strange.

I’m not sure if you’re joking. Phantasms need a target to cast, and since if the Mesmer were to target you, there would be no way for their phantasms to attack other targets other than if they got in the way. Mesmer phantasms are NOT pets, they are spells that take a physical form; a DoT that doesn’t need a condition removal to get rid of. If you see a clone/phantasm attacking your Turrets, the Mesmer probably did a targeting error.

You want to know how to fight Mesmers? Bring a Grenade or Bomb Kit. AoEing down those Phantasms will bring the Mesmer threat level to minimal since the majority of Mesmer damage comes from Shatters/Phantasms and not themselves.

Edit: Wait, what happened to the OP?
