User blog comment:DoctorAsawa/League of Targon's - How Riot Effectively Killed Junglers/@comment-10068022-20131124133931

You are forgetting the thing that if your team has a jungler and you are playing against 2-1-2, your jungler can easily secure their buffs and camps due to dewarding sweeping lense, as well as easy ganks on mid lane, since there will be no one to counter gank. This leads to the thing that there always be 2 people on top so it will be harder for their team to group and team up on drake, since bot lane supports still take exhaust and the top one take smite.

Even though metabreaking 2-1-2 seems quite viable for some ppl, I still think that teams with jungler can get a high speed buff in an early game, due to ganks, control and low mobility.
