So who do you think is the best ganker in game and why? I am only talking champions now, their abilities.

Personally I think I think Warwick cause he is a great jungler at the same time as he is a great ganker with the ulti + movement speed increase when chasing.

What do you think and why?

Amumu jungler is a very good ganker at lvl 4 really... Although i would say ashe is a very good ganker as well...

eve is they dont have ward, if they have ward ww is best

Depends on who you want to gank, and where.

Rammus, Malphite, Warwick are all great at ganking lanes.

It's loads of fun to gank the junglers as Eve or Shaco though.

Amumu, Rammus and Shaco. Warwick can only start to gank efficiently starting from 6 since his ult is his only supressing ability.

But with the first 3 mentioned heroes you have about 99% certainty that there will come a kill if they gank your lane. (assuming they know what they are doing ofc...)

i pretty much wreck anything with pantheon except maybe rammus/malphite in lvl 1-5

Rammus or Nunu jungled up at level 4 are both a force to be reckoned with.

Rammus - powerball - taunt - redbuff
Nunu - bloodboil - snowball - redbuff

Rammus and Nunu are the most successful gankers atm. Shaco isn't bad but he isn't as effective as those 2.

Oh yeah. How could I forget Nunu? I hate that guy...
