Now, I know you other spriests out there probably have your own ideas on what spriests need or don't need - and maybe you're right - but I think this is a change we can ALL agree on.
I'm speaking, of course, about Phantasm, aka Improved Fade. What's wrong with it? Reliability. It doesn't have any.
Anything from a laggy rogue 15-yard autoswing to you just happening to be one pixel too close to a DK desecrate, and the cooldown (plus any talent points you put in it) are wasted. Even coordinated with some form on CC, you can't pop Fade and feel like you can depend on it to help you out. You end up just plain not liking the move.
Well here's something we can add to the talent that will patch this right up (no tears, even!): For the duration of fade, snares cannot reduce you below 100% run speed.
1 - Obviously, fade will always serve you to some degree when used wisely.
2 - It won't combine with the new disc buff (up to +16% run speed), which means that snares are not just easily thrown out (in case there are OP concerns).
3 - Shammy's ghost wolf ability is still unique in that the shaman can keep it us as long as they want. The fade buff's duration could even be reduced when speccing into the talent if deemed necessary.
4 - The effect is already in the game, so it'll be comparatively easy to implement.
TL;DR - Give imp. fade the same snare freedom that ghost wolf has for the duration of the fade buff. It would make our most unreliable PvP talent something we can work with.
