Games feels like if you don't go full damage jungle you will probably not win the game.
Practically every jungle played now and to stay in "Meta" is to go a champion that does high damage rather then tank.
It's all about

now since they deal crazy damage with just 2 items.
What happen to champions like
? Even with their CC with crazy good AOE ult they are getting out perform by damage and thanks to lethality for ADC and being able to be used by all these jungler + top champion they are practically useless at tanking 3 lethality build enemy. I played
and
as tank but now it seem like I have to build AD damage to even matter late game because of the amount of damage enemy does if I don't take them out.
Even the pros don't care to use tank junglers any more with high CC, it's all about damage this damage that and who can delete a champion fast enough.
and
are different, they are played top lane now because that is where they can cs for gold better so they aren't in jungle any more but if they do play jungle then trust me they will fall behind with the damage they do to monster camps and the cost of their item.
Only one that is useful that is tanky is 
seems to do incredibly well as well...
