Alright, i wont suggest here any abilities, and yes, i know there are already frost, fire and arcane mages in the game, yet I believe Millhouse Manastorm fits HOTS perfectly with his story and hilarious quotes.
EDIT: Also there has been Jaina as a frost mage already and here comes Mei, so i think Millhouse also can be another arcane mage next to Li-Ming.
This got me thinking, what would be the difference between hybrid characters and multiclass heroes? Also, why didn’t Blizzard classify Kharazim as multiclass too? Lmao
