Skill Bug?

Is this a bug?:

When I run towards an enemy and he casts water trident, I hit escape (stop action) way before it finishes casting, let alone having hit me, yet it still knocks me down.

As the skill states it knocks down if target is moving, yet it knocks me down when it hits me if im not moving.

Maybe u got some lagz?

I don't see this being a bug. But srsly, if you have huge problem with it go to:

and they can solve it faster. Or try to do something else to dodge the projectile.

It may be that it works like melandru's shot, that is the knockdown is determined whether or not the foe is moving when the spell is cast not necessarily when it hits the foe. I think the same is with crippling dagger aswell.

Just dodge it instead of wasting time to stop.

I dont think water trident can be dodged, it moves too fast

it's a projectile. speed is irrelevant because it'll automatically shoot for where you *should* be, based on your current movement. I.E. run left, at the instant it's finished casting, reverse direction 180 degrees.

Always functioned like this and its not a bug although it would make that much more sense it it checked for conditionals on hit rather than on cast start.
Same goes for the rest of the same type of skills.
