Anyone who can abuse it's stupid health-mana link is now OP in lane. It's not a balance-able mechanic and it's going to ruin the game the same way that the old season 1 item did (can't remember it's name). A bunch of champions are going to get "balanced" around it, then it's going to get removed/reworked and a bunch of champs will be dumpstered like yi is right now.
Riot, break the cycle and just chance the item, not the champions.
An item that requires you to get damage to get mana back is broken? You don't even get that much mana back from getting chunked. If you get critted for 1,000 you only get 150 mana because you turn 15% of damage taken turns into mana. As for the health return for mana spent/damage dealt, it's hard capped at 50hp. Guess what? ADCs heal up to 300 or even 500 when low, crit, and have warlords mastery. ADCs don't even need to spend mana. How it RoA broken??? One could argue that its underwhelming.
lol ok. check out guinsoos on vayne.
