'Warlord's Bloodlust' Keystone is too Strong.

I've had several discussions with a few of my friends of both equal and higher rank (up to Master) about this Keystone Mastery and how strong it's made champions that are based around Critical Strike.

It needs a longer cooldown on the Heal/AS Proc it grants, a 2 second cooldown is nothing for a perk that heals you for 15% of the damage dealt, and grants you 20% increased attack speed for 4 seconds (2 seconds longer than the cooldown).

There's the obvious perpetrators - Yasuo, Tryndamere and Master Yi - but there's more than just them.

Very recently, I had an allied Master Yi Jungle who was healing (From what I could see) up to +453 health every 2 seconds with this mastery, and +128 health every autoattack with Death's Dance.
