Arcane Torrent restores 3% of mana or grants 15 Insanity along with it’s other use. It’s worth having on the bar for emergencies or trying to get in one more spender.
I’d go the other way. Racials should be strong enough to use rotationally, and they should be mega different. A Tauren should have more strength and stamina than a gnome. Period. War stomp could be pushed out to 5 seconds, escape artist could grant immunity to traps/snares passively, etc.
They do have base line stats for each race. Nelfs have more agility tautens have more strength - I don’t know if this is still the case but I like this little touch.
The disparity was close to 5 points extra, so again very minor but it was in the game last time I checked (I could be mixing up classic)
