Can someone explain wtf they were thinking with warlords bloodlust/crit?

The biggest complaint with crit is that you can win/lose a duel based on it. If you get lucky and crit a few times or not.

So to balance out the randomness of crit they decide to also add lifesteal.. when you crit?

I swear when I heard they were addressing crit during my break after S5 I didn't expect to be trolled by riot lol.
