If R/M/E were in terms of dmg/skill between 113 and 119 they could be still powerful and asked again to endgame events. Some of them have really nice abilities that i believe it would outclass some 119 weapons.

If they just make them 119 then all new content will be trashed in favor of old content. That wouldn't make any sense for a game genre that should always be looking ahead and not backwards.
