Today i played as Morph, and as we know if morph is stunned u cannot gain agility or streinght as long as u are under stun, wind shackle works as root (strong disable) and While i was shackled i used streinght gain and there was no animation over morph (brown aura around hero for streinght gain) and after shackle duration my morp was insta on FULL STREINGHT! i was like wtf.... no animation, no swap on atribute numbers but insta swap the from 0+... agility to max + streinght.

I think this is a gameplay bug, and valve will fix it.
