The Chosen Ones

I think its just personal opinion which and which skills is better. Every skills are better at something. Maybe the worst skill is fradz skill which use distant to increase damage like wtf he is a melee hero.
That's the only skill i can think from objective reasoning.

All other skills have situational time when you can use it effectively and where you don't like galeoth frozen wave which make him stand in place and vulnerable to attack but deals unusually large magic damage and chills of the frost master which really powerful if you use it right.
