Many of WM skills has long animation, which make them too easy to attack while the animation is running. With this skill canceller, they can cancel the skill even though they have finished casting it (but the spell has not been casted because of long animation). The skill should still need to cool down even after skill canceller.
And i think all of the animation canceller should be changed into skill canceller (one example has been stated by Flovios, sword dance).
2. WMs time freeze. I realize it got nerfed after Christmas patch (or bugged, idk). It stop some player for 4s (which is normal), but to some other player it only stop them for 1s (still figuring out why and when this is happened
