said by Tweakbl:Darklogix, I understood it not so much a tweak to make it easy, but a tweak to allow running them solo out of a raid group. So those that do not wish to have tag alongs and want to solo it can do it in regular groups instead of Raid Groups.
There's that
there are two things in the blue posts
non-grouped players my enter old raids
and
some raid bosses have been tweaked to make them soloable.
IE the only specific one I heard about was BWL where they nerfed the health on a boss and damage so its easier for a single person to do the MC of the boss without wiping.
