it is strange that such a nuetral champ would pick either side

He must have promised Morgana's Cookies.

A female armadillo. >.>

They just asked him and he sayed:

"OK".


And how the heck did you came to the conclusion that sideing with Noxus is against everything he stands for?
Thats just stupid.

Not really, Rammus is pretty much "Ok" with everything.

Well... here's a short but good explanation. :P
