Kedge Keep is still viable up into the 50s if you want to get ballsy and do the Seahorse Caves (lots of wizards, cleric, and druid mobs hunched together though). At 51 it's nearly a % per kill (pretty much every kill was a %, some weren't - keep in mind 51 is a hell level).

You have to use a bit of tact to split it effectively, but once you break the spawn it's a cake walk (just keep yourself bound outside and a gate ready. Also, extra fish scales stashed away somewhere since it's a bit of trek in to your corpse if you get popped).

At the same time - 51 - there's spawn down the tube at the entrance that still are lb/db and provide decent xp as well (without near as much risk).

I find the seahorse caves more engaging and fun though.

And yeah, Cauldronbubble is soloable.
