[BUG?] Cooldown spell not cast and cooldown applied when dashing

I noticed that when I cast any spell that has cooldown and I immediately dash then the spell is not being cast, animation is being cancelled but the cooldown is applied. This is very annoying as why we're being punished by this? Spell is not being cast but we need to wait for a cooldown...

Also mana is not taken from us so why cooldown is applied?

Bump up thread

Yup, I have the same issue with one of my spells:
My Orb of Storms has +6 seconds cooldown and 0.57 cast time.

If I cast the spell and start doing another skill or dodge roll within that 0.57s window, the Orb is cancelled and cooldown is used up.
Same goes for being stunned.
Since the cooldown is so long, this can basically lead to death.

Effectively I am forced to always cast this spell super carefully, without touching any other buttons until the Orb appears, otherwise it would literally feel as if my keyboard is broken and actions are not registered.
