i would prefer a slow down as well, or the ability to interrupt a spell completely based on a skill specifically geared towards interrupting (ie, rogue kick
) but, its only up to level 10 at this point. there's so much combat and abilities we've yet to see.
and where is the 'rune' casting bar? :O i liked the fact it was scripty and looked like a spell being spoken instead of a cast bar. an in-game option maybe>
