Suggestion is simple: give us a keybind, similar to ‘Target Next Enemy’ but which only targets players and mesmer illusions which share the name of the player (ie not Illusionary Duelist, etc).
What would this do? It would allow fighting minion masters to be significantly less frustrating. Targetting an Asuran Necromancer among their plethora of minions is a daunting task no matter how you slice it. In WvW, targeting players among the mass of necro, mesmer and ranger minions, illusions, and pets can be extremely frustrating. This would help alleviate that.
Why would Mesmer illusions still be targeted? They’re part of mesmer’s defenses. Allowing players to effectively bypass them would be crippling to them.
