RChu1982: While doing quests is always good, at higher levels, the XP rewards for doing quests are a drop in the bucket. Instead, the Mountain Wilderness gives high-level, high-XP spawns (level 34 Molten Scorchers spawn here). They are easily countered, and give good XP (This is not a rare spawn; They spawn a lot if around level 34).
If you get the XP rewards when they're still significant, you will get some levels sooner, which in turn causes higher level enemies to spawn sooner, increasing the rate at which you earn experience. It's like exponential growth: If there's a fixed boost you can get, the long-term benefit of getting it early will be significantly higher than what you'd get later.
In particular, if you're going to speedrun to, say, level 30 (or higher, of course), the strategy would be to try and do the XP rewarding quests as soon as possible (or, alternatively, find high level high XP fixed spawns and kill them early, but that might not be so easy), then kill the stronger enemies that spawn for more XP. (Alternatively, you could take advantage of the bug that makes high level enemies spawn when you're below the minimum level for the area, but actually killing those enemies and surviving isn't exactly trivial.)
