Not only the summons attack other players , but also the player it self. My own summon killed me. This is very big issue since it forces the wiy/witch play without the summons or really remember to put them out when it comes to boss fights.
This has been an issue since I started playing (about 4 months ago). If anything, I would maybe consider this a critical issue since this prevents players interested in Wizard’s and Witch classes from playing them, and also cuts down a good portion of their dps at world bosses which is needed for higher chances at better loot.
