They won't remove it. It's too much of a hassle to drastically change "old" content. It's not justified by their budget.

"Oh, but all they have to do is remove this 1 line of code right?" I seriously doubt it's a simple thing to do. If I were to guess, I'd say the GC thing is probably nested pretty deep in the system. If it had been simple they would have done something by now.

Taken how "hard" it is to do something to the GC system, and the popularity of PvP in this game, the ones making the calls deem it not worthy to include GC removal in the schedule. There is probably more to it, but this is basically how I view it.
