Anyone else feel this way?

Level GLA to 50. Oh I should get stone skin! Hmm, but I also would like mercy stroke, okay got that, guess I should get him to 30 incase I want to warrior, but I guess that means I should get a PGL up so I have feather foot for cross class. Okay start PGL, guess I'll get him to 30 incase I want to monk it up, better level a LNC to 15 for that too!

Oh but now I forgot about my Armor smith! Better start leveling other DOH classes for cross class!

Etc etc etc...

Why is leveling addictive? It's not supposed to work this way, SE!

Haven't actually done most of this stuff yet, but all I can think about while leveling is the next class I'm going to level. Which just adds to the vicious circle.
