The only thing the jungle changes did was force junglers to play early game duelists.
You literally can not play anything but an early game duelist or you will get fucked in the ass and expected to take it, because lord knows you can't verbalize your frustration in game. Nope that's bounds for getting banned if you get angry at Riot's infinite wisdom! Nope, you have to sit there and just let the enemy jungler who played a duelist shove the dildo farther and farther up your ass. Just sit there and take it, and enjoy your jungle diversity of xin, graves, udyr, jax, kha.
