Here's your rescue!
With this new crit system, everything has the same rating, spell crit is melee and vice versa. This makes my warrior having 19% spell crit, thus my intercept ability crits 24/7.
The thing I mean with this, is that you would probably be able to SILENCE intercept.
Imagine this. You are a Blood Elf mage, lvl 70 pvping in arena or whatever, and this warrior comes to you and charges and stuff like that. When he runs away for brining an intercept up on you, just do arcane torrent and he wont be able to intercept you for some time (I believe it is 4 seconds).
GL owning warriors!
