I was pvping with KR and the last target function is a bit funky. It counts target self as a target so if you hit your target self key then it switches yourself as the next target. As you can imagine this is quite annoying when it comes to anything because you might be using last target to fire spells at something and then heal yourself and pull up another flamestrike and your last target hits yourself. It would be nice if they fixed it to where it was like the 2D last target and perhaps make a "que last target" key to compete with the ones that are used in UOA and other third party programs.
