Rammus hidden OP?

Here is the easy champ what can kill anybody while building tank/magic resist.

Rammus is one of those champions what you don't see very often but is now very good or op champ in this moment. Link of that game is just a one game where i make most of the dmg while being only tank. I could show more of these games where i did most of the dmg, but in this one i did insane amount of dmg (One reason is that they had double jungle).

You don't really need any skills so this champ is good choice if you climb in low elo. ( i don't know is this good at higher elos) And making good grades like s is very easy. You dont have to be afraid of anything while being Rammus, because in most of the games i see only ad teams who had max 2 guys whit ap. Its hard to counter Rammus because there is not good counter picks against him. I think players doens't know what Rammus actually can do and it's too late in game when he kills you while being full tank. It's hard to lose 1v1 while being Rammus in late game. Sry my english
