During Ash's Ultimate ability she is not CC Immune, Makoa can Dredge Anchor her out of her area and Bomb King can stun her with Grumpy Bomb. If she has the Battering Ram legendary she will use this to escape the stun and therefore be out of the area!

Jenos can 1v1 weaker enemies very well, he can pump out some decent damage and then use his Void Grip to allow his teammates to gank you. If you are able to, try to continually shoulder peak him so that he can't Void Grip you, or take a teammate.
