Macroing mark with tomahawk/shield lob is a bad idea. Say you want to mark something else mid fight, you may have just wasted 120 tp. Might need that tp in long fights or to start the next set of adds quicker.

Honestly, most DPS should be capable of watching which mob you attacked first and burn it down first then go for lowest health. Meanwhile I'm securing hate on the other adds so said DPS can go all out on their next targets. I don't lose hate, one mob dies so the healer can throw out more DPS instead of spamming heals on me and the DPS can maximize their damage in any way they wish.
