He liked it a lot. Says it leans way harder into Diablo 2 than Diablo 3.
Specific notes:
- Classes are not gender locked
- There is some character customization (choose a face & color)
- Dodging mechanic feels solid and fun
- They only had barbarian, sorceress, and druid so far
- He played druid, said it's like a barbarian with spells and pets and you dynamically shapeshift during attacks - like start off with a wolf melee attack and shift into a bear move in the middle
- He joined in killing some world event boss and said it was an awesome fight. The boss was destroying entire groups of players. (aside: yes, it's more MMO-y than previous Diablos, but you can play solo)
Now just have to wait another... 3... or 4... years.
