This is how i have been playing Rammus for the last few days and i wanted to share my love of this champion/build. Can be played top or jungle just swap ignite for smite.

Pros:
Does lol tons of damage
Pretty tanky
Dunk ad tops
Dunk non ad tops
Gets underestimated a lot cause you are small

Cons:
Not as tanky as the "Meta" Rammus build
Can be kited like all melee champs

Rammus's W does magic damage so it procs the damage from liandrys and because its a spell it procs elder lizard. Combined that with sunfire and defensive ball curls base damage AND auto attacking with the wits end to lower their MR while you have almost 250 AD because of your passive and lizard elder. Just dear god.

Hit Q, when you run into something hit W.

When going in to kill a tower hit W to get more AD and R because it does damage to towers and it scales with AP so with our items it will dunk towers.

Hit Q, when you run into their AD/AP carry hit R then W. When the try to run, and they will, hit E.

I hope you all enjoy this build as much as i do and if you don't then that's ok too. I will update this guide if it gets some decent up votes.
