Isn't it time we re-enabled Bloodthirster on Dominion/TT/ARAM?
The original reason that Bloodthirster was removed was because it had a stacking mechanic--it gained power when you killed minions, and it lost some of that power when you died. In a low-farm, high-mortality environment, that was a bad deal.
But new Bloodthirster, with its overhealing shied, is a good sustain item that no longer has an enforced snowball mechanic. Shouldn't we go ahead and enable it? Sanguine Blade is really not a great substitute, and with the BT changes it makes sense to switch it back in.
