The old Zul'Gurub used to have this exact lockout system... although I think the days were different. It was like Tuesday at 4 am and Friday at 4 am.

Those of us praying for tiger mounts would solo that bad boy twice a week. Never got it tho /cry, and the panther thing that looks exactly like the night elf mounts frankly is straight lame compared to the zulian tiger.

As far as Dragonwraith, it'll still take a long time, but I'm of the opinion it takes non-elite raiders too long to get legendaries. With the exception of 1 horde guild on my server, everyone on my server got Shadowmourne well after it was really necessary for dps checks. And plenty of people never got it. Let's not even talk about Val'anyr. People who have and are getting dragonwraith by now have been doing firelands for what, 5 months? That's a crap-ton of raiding and time... and just simple grinding.

Frankly I think the "farm a raid for 1-2 months for legendary shards" is real crap when it comes to legendaries. I prefer more of the "do something special during a boss kill" type thing. The optional boss thing is cool too. Farming for materials, go do that for crafted epics. Leave it out of the epic questing for a legendary, please.

Anyway if this helps a few more people get a legendary at this point, I don't see why you (or anyone) would have a problem with it. It still takes a crap ton of effort, and the total time you put into getting it doesn't go down (it's just that the time you put in will now be compressed on the calendar).
