Vanguard has sooo many bugs, mostly small but still annoying, and their team resources are so limited that they have to triage defect repairs. There is no way they can repair -- let alone identify -- all of them. Triaging based on player-influenced priority is a reasonable method to avoid wasting resources on repairing defects that few people care or even know about.

A shame, really, because Vanguard has so much potential but it is highly unlikely that it will ever be realized. Server populations appear to be growing slowly -- without any apparent marketing support from SOE -- but I believe that SOE management has already written off Vanguard as a "loss" and it will eventually be shut down to re-redistribute the resources (people and hardware) to newer or more profitable projects; just like what happened to Matrix On-Line.
