DW was one of the aspects, hence dragonblight and the wyrmrest made sense. Alexstraza and the rest of the aspects are seated there....so hence the re-use of dragonblight, same map but different setting altogether with the Maw and everything. Dragon Soul wasnt bad nor was is it good enough but I cant think of a better way of doing it than this.......They introduced the concept of extra action button and its very obvious that spine of DW was the main feature of the raid and I believe they gave too much time for that fight alone.
The raid sucked because it lasted for 10 months and the nerfs came in too early imo. Otherwise it was not that bad.
And about the siege of orgrimmar, i think its better if we dont discuss this at this point. The files from the ptr lead to garrosh being the bad guy and i m looking forward to punting him out of this world, but there is alot of content to enjoy at this point.....to compare DS with a "assumed" raid which hasnt been discussed by blizzard yet. We knew from blizz con 2010 that there was going to be a fight on the back of DW.....no word from blizzard yet, so let the files atleast appear on the PTR.
