Jungle and Mana Changes Instead of AD and Crit... Why?

I can kind of see where the jungle changes came from "New map needs new jungle gameplay", although i don't think anyone really asked for it.

The mana changes also came out of the blue, but for a good reason, though the reasoning behind why they were in the state they had been in was because of manaless assassins or fighters having a feast of mana heavy users in the mid/top lane, because they could sustain for much much longer periods of time before recalling giving them the level and farm advantage.

AD casters still stomp on tanks because of Armor Pen and , then AD still gets some of the best itemized options in the game, .

Crit is still insane. It's that simple, buying an Alone puts AD champions in a position where they will randomly (based on their crit chance) hit the target with an auto attack that's equally as strong or stronger than a CD based skillshot from a APC stacking AP.

I think that this has more to do with how insane crit is rather than the stat alone, but lifesteal is absolutely insane right now too, a single auto attack in the mid game can heal for over 100 health easily, which calculating HPS (heals per second) is higher than most every champion with built in heals.
