Am I Losing It? Where's The EXP?

[Rastignac]

Last night I was playing my cousin's Erudite Enchanter. He's level 12. I was killing mummies and skelies at the undead tower in LFay. I was getting no more than 1 blue tick per dark blue con! That seems crazy to me.

Beforehand, he was playing his toon while grouping with my brother, who is a level 14 Necro. They were at sisters. He gained only two yellow bubs in the time my brother went from 14 to 15. Brother is an erudite too.

I may just have been away from the game too long, but it seems like he is leveling far more slowly than those around him.

Thoughts?
