Good info.

In my opinion, Stormy is also excellent in GW offense, in particular against dragons.   A lot of people hide Skeletica behind a wall and relatively alone.  A group of heroes led by revite 5 Stormy can break that wall and have Stormy stun the dragon.   Once stunned, dragon often becomes easy prey.

I haven't tried Stormy on Lavanica, but I tried it on Molt and Skelly, and had good experiences.   I know Dove has a reputation as dragon slayer, but I think Stormy deserves it as well, maybe even more.
