Heroes of the Storm Forums

So I've played in a number of games now where Murky has absolutely dominated me with Octo-Grab (I've been playing squishier heroes recently that can't withstand much of his Pufferfish -> Octo-Grab combo).

My question is: is Octo-Grab reduced by talents like Relentless? Does it respond to Cleanse? It seems to me that it's a bit more of a unique heroic in that the stun is unavoidable, but maybe that's not a correct observation. How do other players play against this stun? Am I alone in my troubles with this heroic?
