I think its just we've all heard the feed TP arguement every time the word melee and RDM are used in the same sentence. I know there are situations you just outright shouldn't, and those are the ones no one will be meleeing on anyways. But in this day and age with X-hit weapons and DA/TA traits/atmas/gear, having just 2-3 melee on a mob makes the TP arguement almost entirely moot.
