Dear Riot, thank you for taking my idea into account (+5 damage on minions on Doran's Ring)
Currently in PBE right now:
Doran's Ring No longer gives base mana regen* No longer returns mana on minion kill* Now gives 5 mana per 5 seconds* Now gives +5 damage on hit versus minions*
Although it's kinda sad & unexpected to see a bunch of Mana changes going on, I'm glad they're at least helping mage players to last hit better to rival alongside Doran Shield users.
