not sure if its been posted before, but I just ran into this and I'm not sure i understand what exactly is the reasoning behind it. I cast an ability on a mob - they should be tagged by me, instead of being subject to kill stealing, while I deal with the rest of the mob group.

or is it too much to ask for?

(I'm actually enjoying the game immensely and this is the first issue that I ran into that I would actively want to be changed)
