Like I have suggested before, in order to fix the rendering problem with thieves, and the zerg in WvW or costume brawling in lions arch they needs to first add nameplates, regardless if the character model is loaded or not the nameplate should be up
For an even better solution, nameplates as well as a very low res shadow version of the character should be in place of the character until it renders.
As for the hacks…Anet get on it.
