Is this intended?
It’s intended. Steal can be cast during any attack and while stunned, much like warrior shouts or traited meditations. Personally, I think it’s fine, but to each their own, I suppose.
Even if it is not intended it adds skill to the game so you should fully support it. I dont much like theives but being able to do that is great, just like a Ele can teleport just before finishing their aoe to hit someone quite reliably.(even tho the ele thing is MUCH easier to pull off)
No different than Churning Earth + Blink, stomping + any blink, etc.
