BoC and BoW both weren't warrior only. One of the guilds on my server at the time had a ranger grab their first BoW to protest them not wanting to make any class restrictions in the DKP system for (actual) bows.They've always had them really. Blade of Carnage from Velious, Blade of War from PoP, etc.
Rogues it's just Sony being retarded and not being able to balance classes' damage outputs without giving rogues better ratio weapons. I would expect this to be the norm for berserkers soon as well.
