In 5v5 you can't CC or lockdown everyone capable of CCing the rogue, and he quickly becomes useless against organized teams that know how to control rogues.

Warriors, the other melee class, have the best abilities to break and become immune to fear. They can also intercept to close the gap when being kited. Also MS is not dispellable, whereas wound poison is.

Rogues are very brutal in 2v2 and 3v3, but a lot like druids they lose a good portion of their effectiveness in the bigger fights. However, I do think that a 5 stealth team in 5v5 is something that could be explored more, especially with the growing popularity of all cloth teams to counter MS warrior/paladin teams. I can only imagine the chaos caused by multiple shadowstep rogues bursting down one person, then vanishing and repeating, to turn a 5v5 into a 5v3 very quickly.
