Accelerated experience 1-60 next patch?

The leveling curve and quest experience decrease/increase (respectively) will not be in the 2.2 patch, which is technically the next patch. If you're asking will it be in the patch after that, we haven't announced exactly when the feature will be included just yet.

Almost everything Kevmar said was wrong though, fyi.

The increase stops at 60 for both reduction in XP required for each level, and quest XP increases, so if your alt is 60 then you should just level them now.

Q u o t e:
If you get a 30% increase in exp for quests then you will get less rep because the quests will go grey before you can do them all. Hunters will really be messed up because they will level twice as fast as thier pets. So are they going to start giving full rep for all under 60 quests like they currently do for the starting zone quests?

I don't believe a percentage increase has been stated. Reputation has not been reduced relative to level difference since (I think) patch 2.0, and that applies to all reputation gains anywhere, not just starting areas. I don't think hunter pets will be an issue either.

Q u o t e:
The faster you level the more gold you need for buying spells, skills and equipment. Are those without high level characters to bankroll them going to be stuck farming grey MObs for the gold they need for training? Or are they going to be incresing the rewards you get from the quests by 30%?

There's no change to loot or quest rewards. I know some classes have higher training costs than others at some level gains, and if it looks like it's an issue we can make adjustments to those prices.
