League of Legends (LoL) Question: Jungle Alistar [Season 4]

It works but it's not too strong compared to other picks. Alistar is also a utility gank pressure jungler, which is the kind of jungle nerfed the hardest in season 4. Farming junglers will outscale you really fast unless you get a ton of successful early ganks off.

Considering that in S2, his passive was nerfed in a way that prevented him jungling and in S3-S4, the jungles were made stronger and punishing for champions that clear the way he does, it really stands to reason that he can't jungle well primarily because of his slow clear.

It works if done almost perfectly. I did a whole guide on it in S4, if you want to check it out.
