Mutalisks in ZvZ

Hi there everyone, I'm a gold league zerg player who's recently been having a LOT (and I mean a LOT) of trouble with mutas in ZvZ. It feels like they've completely overtaken the ZvZ metagame and ZvZ now just comes down to whoever can spam the most mutas. That may or may not be true, but it certainly is the impression I get from my recent ZvZ games.

In the past, I used to counter Mutas easily with hydras + fungal growth combo, but ever since fungal growth is a projectile and mutaslisks' movement speed has been increased, it has become so much harder to catch them with it; and with their new regen, any amount of damage dealt feels worthless so long as they're able to escape before dying. Is it just me? Or does anyone else agree? I'm not really whining; I figure there must be a potent counter to them... I just don't see it. :(
