Ah, I believe DAOC had /stick which would let you melee (possibly WAR as well), but I don't do melee in other MMOs because it's virtually impossible to melee moving targets. I never used melee in WoW either, only ranged (except for the main).

I use IWT only for NPC interaction and looting, and for that purpose you don't really need CTM. But what is really like with this and looting is that it does AoE looting with a single click, for your whole team.
