Bloodlust & selection scale

Why when I add a bloodlust ability [Ablo] to a unit (in my case it gives 0% movespeed, 0% attackspeed and 200% scale), the units selection scale changes (when I add the ability, even without casting it)?

Did someone have the same problem or I am doing something wrong?

add dummy spell and dummycast actual ability.

Bloodlust has autocast, I'm not sure anything could substitute it properly unless you mean add a 0% increase to scaling and then add proper scaling.

inner fire have similar AI, you can use this spell and dummy ability.

No its not a problem, I did the dummy spell already and it works (I'm not concerned whether it has autocast or not).

I'm rather concerned why it does that. So it actually happens to ladder orc shamans?

This is same for dota, and other maps, but, looks like shamans have proper object settings and this is not visible on them.

I wasnt able to reproduce problem.
