Clean up on your epic quests. Level 30 characters can enter any level 24+ quest.

A first time run thorugh High Road on R10 is worth about as much rxp as a repeat run on a legendary quest on r10.

This is a good way to get used to higher skulls without being crushed by Sharn or Feywild mobs. It can help your alts get those first 25 points.

I have been doing this with my guildies and it works really well.
