The difference in damage output when in your tanking stance between a War and a Drk is only 2%, not including things such as Unchained, Berserk, and IR that the War has which gives them the edge over Drk.
Darkside is not a unique concept that only we have, don't know why people think it is. I guess it just stands out too much seeing as it's a stance and not a refreshable buff through a rotation like Maim is.
So yes, the other tanks DO get that damage boost.
