GL's like many systems in this game were decent ideas, that were piss-poorly done. i think they are fine, but not as a prime thing. I always thought is was going to be a side thing, meant for the casuals or the occasional quickplay. In the end they turned out to be the only solid way of gaining much of anything. They need to re-balance them, add new ways to grind, make camp grinding worth it and have them be what they should have been in the first place....a quickplay thats used on occasion.

If you want a comparison, compare it to FFXI's Fields of Valor. Its there to help out solo play and its (was) limited because they didnt want everyone to spend all their time doing it. It was useful enough for what it was, but not big enough to take away from the most productive way of leveling.
