Fortunately I have a Pally bot that will keep the mob busy while I sit/stand/turn attack on and off/cycle through mobs/assist Pally bot and all the other things I have tried, but there is no sign of me entering combat.
I can kick a mob fine (and other extras) but just not melee at certain times. Sometimes it will kick in when the mobs at 15-30% hp left and Im hitting as normal. When Im close to the mob I get nothing (no 'Cant see' type warnings) but if I move away, then I get the 'out or range' warning.
Really stumped, but had this alot lately

Any ideas?
