how do you pronounce "Suriel"?
Lion is pretty simple and has an interesting kit with lots of disable.
witch doctor
Yeah, Witch Doctor is good. A few others as well.
Vengeful Spirit - Single target stun, point and click, simple.
Ogre Magi - Another single target stun, point and click. Can have two of them with Aghs.
Tidehunter - Large AoE ultimate stun
Sven - AoE stun
Lion - Line stun, I don't know if hexes count for that objective, but he has one of those too.
Shadow Shaman - Has a single target channeled stun, also has a hex if those count
Lina - AoE stun
Thanks! Will check some of these.
