Fysi>> Doubt it really. They would probably have done it sooner, but not wtfpwn the strict guilds. It's a really different game out there where you have to fiddle far more with gear and have far less room for failure due to not being able to take the better of both worlds.
And Paragon, like Ensidia, di the 25LK kill AFTER having killed the LK10 with ICC25 gear and being geared up in 10 hc gear AND ICC25 gear, not the same thing once again.
Being able to run 10/25 at the same time every week (like most raiding guilds do) means they gear up FAR faster (emblems and drops) and have the choice of everything and twice as much chance to put their hands on a needed slot upgrade....
It's what most people fail to realize.
