I honestly dont feel that cavalry have ANY way of killing me if Im aware of them, except by bumpslashing, and range doesnt really matter then XD
Of course, a gank is a gank, and then you cannot help yourself sometimes, but since there are no longer any crushthoughs from horseback, as long as you see the cavalry coming u can jump away from couches, and block all other attacks. WORST come to worst, and you are being repeatedly ran over, find a tree, rock, sudden change of ground angle, fence, wall, etc and suddenly YOU have the advantage vs the horseman.
