guild you've been in for a year

100%!? That's like... all percent.

Well, I think this is a valid complaint being that there's an initial buy-in period where you're kind of wondering why you have to level up reputation with a guild you've been in for a year, but that's sort of the nature of implementing new features like this.

You are correct in that best wow gold site we do not want people to join guilds, be able to immediately buy rewards that the guild unlocked, and jet. Your idea of unlocking rewards based on time spent in the guild instead of contribution isn't quite right either.

Guild rep exists to gate rewards based on someone's actual contributions to their guild, not just being some dope on the roster. Jumping in to guild dungeon and raid runs (with 80% members, [25% for 40 person raids] until 4.0.6 which drops 5 person dungeons to variable gains based on 3/5, 4/5, and 5/5), winning rated bg's, or earning guild achievements, all help earn guild rep. And yes, so do quests, should you find yourself doing them.
