Yep with mesmer or ranger it's very easy to solo Glint with henchies. With mesmer Wastrel's Worry is the skill that gives the heaviest dmg to Glint. My gf used mesmer and had two henchies alive after Glint was dead.
According to the Guild Wars box it is "Join with friends or play solo with a band of skillfull henchmen" It says that Above Hoh Picture and below the Warrior with a hammer and Knights armor, and to the right of the female warrior wearing knights armor battleing a freocious drake in Kryta.lol
I think Glint is completely against solo builds killing her
Crystal Bonds sees that through on its own. What is it, target loses all enchantments and cannot be the target of further enchantments for x seconds?
Its like trying Dunes of Despair bonus with henchman I spammed Wastrels Worry just enough to kill the last boss, 10 seconds later the Ghost dies, hehe.
