I'm excited for the new Essence Reaver

3620 mana 2990 health 231 armor 109 magic resist 291 AD 2.39 attack speed (1.76 attack speed accounting for cast times)

3 second stun cooldown which lasts for 1.25 seconds 43-217 physical damage on hit (muramana) 36-0 mana gained on hit (essence reaver) 113 magic damage on hit (passive)

Assuming 50% mana, this is 1150 dps, 170 healing per second, and 188 shielding per second.

I thought I should mention that the biggest reason I'm looking forward to this on Taric is that Taric has severe mana problems. It isn't so much the cooldown. His stun cooldown just goes from 4 seconds to 3 seconds which isn't a huge deal. With 36 mana per hit at no mana, he gains about 71 mana with his 2 bravado attacks. His w and e cost 51 mana. This means that Taric can literally spam his abilities forever with this. He used to be able to do the same thing with the old essence reaver but it didn't work on towers and he would have to buy another crit item to really make use of it. I predict that with this build, Taric will be able to march it down mid without buffs or minions and take all 5 towers without backing (in practice mode of course).
