This would be cool.

iirc enemies can take fall damage. the most common cause for enemies dying from vortexes though is them landing on a spot they can't navigate from

Admittedly it has been a couple of months since I played, so maybe they don't die from them (Though what about Halescourge's huge vortex?) but they 100% throw all smaller enemies that enter the vortex.

Vortex may pick up enemy mobs but it doesn't damage them.

Except it doesn't. Small enemies get thrown around and killed by Vortexes every time one of those pesky brapstormers conjure up their smelly tornadoes.

Vortex is pure magic. So it is normal that it only effects the Players.

It would be very chaos of them to make this the standard

The problem with this is that the devs legit didn't program in animation for enemies like the Chaos Warriors being thrown around only the stumble. So making this sanctioned would only serve to highlight a bit of incompetence.
I'm sure they could put in a small animation like that so this might get implemented in the next expansion.

Sanctioned this bitch devs! (ik it won't happen, cause then a Blightstormer would infact Save the group more than hurt it 8/10 times)

The chaos helicopters are comming! Ring the bells!

what

I think THAT makes sense! How many times have I been angry, that only I have been whirled around - and e.g. such a small rat(s) is not...
