First off dota is SOOOO Unbalanced your lieing to your self if you think it is.

I dont keep track of it sence its been high-jacked so many times.

If I recall the void is a spell caster currect?

In that case ANY non int based hero can take him.

Mainly go for alg bases heros sence there more rigged than the others. Find a good hero that has windwalk and critical strike or maybe a long range stun skill.

Theres so many rigged skills in this game its hard to find wish is more rigged sence it changed from ver to ver.

Of course the smart thing to do I quite dota all together.
