There no platforming on Assassins Creed. Unless you guys call wall shimmying platforming.
IMO, 3D platforming is what Mario does.
I tend to agree, but AC does at least try to spice up the climbing a bit; for example, the newest one (Revelations?) had that hook thing that greatly increased the amount of wall you could scale with each leap. I'd like LoS2 to do something similar, just make the wall navigation smoother and much more agile.
More than this platforming, what would be awesome from AC in LoS2 is the sheer scale of architecture you can climb, which would be amazing coupled with, say, the Castle part (provided the inside is as big and intimidating as the outside).
But I'd heavily prefer the "jumping between platforms" kind. I did love the parts of running across water in the Reverie DLC... that entire part had me humming the Stage 4 BGM in CV1.
