Only if I see something big and glaring. To passive aggressive for anything less so I let most things slid as long as it doesn't break the fun. 

Btw, in terms of prepping attacks, you should know that when a charcter is prepping for their special ability they usually can't also use it during that time. So while a mage can chant a words to a spell and swing with a sword, he can't power a spell and use another spell while defending. Else that would obviously leave huge room for abuse. So if Khold used wind to slow his fall or speed himself up, it would have reset his most recent prep, though changing his prep would have probably done that anyway.

Also- So Khold went to another platform altogether yes?
