champion buy

j4,lee sin,sejuani,wukong.

Lee sin has good early damage and can pull off amazing Insec plays, Jarvan has amazing ganks post 6, Sejuani has so much cc that its ridiculous. Thats about it in the 4800 range.

save up 6300 for vi.. bitch is freelo

4800? Uh get shyvana. Especially with the new sated devourer, shes INSANE right now. Get a bork, randuins, sated devourer, merc treads, ravenous hydra, and a GA. easy game trust me

Honestly there are so many options right there. If you like tanks, go Jarvan or Sejuani, still pretty good, I'm personally a bit more of a Jarvan fan. You want a bruiser? Get Lee sin, or save up for Vi. My favorite jungler is Rek'sai, not too hard to learn, pretty easy to gank with, does so much damage. Shyvana also a good hybrid tank if you're thinking of getting her.

Ok guys i think i will save up to 6300 and buy hecarim but is he good in the jungle or should i buy another one? Thanks :)

good ganks and good cc and solid damage

I recommend either one of the following:
All 4 champs have great crowd control (stuns, knock ups, slows) and very solid damage even without damage items. Gragas is another good jungled right now in the meta.
