The cage allows wrestlers to use it as a wall and has the disadvantage for strikers at least stalkers that they can't back a guy into the corner cause they can always circle out. Counter punchers again have the advantage in the octagon in that they can circle out, they always have some place to move when the aggressor comes ahead. Cro Cop was and still is a stalker and the octagon was never suited for him well because of that. Judo (to a lesser degree Sambo as its judo based) guys are another group at a disadvantage in the cage becasue some trips and throws are just harder to get off in a cage with his opponents back to it, Ropes don't offer the same structure.
