i left my macbook on all day (9am until 6pm) while i was out and college and such, and still waiting for it to finish now at 11pm.
ive had a look in the 'available' state, and personally, i hate it.
can see myself quitting wow soon.
they ruined paladins, nerfed stamina, ruined most talent trees and screwed up raid lockout :/
but seriously, paladin tank aggro is now weak-as, stamina is overloaded onto all gear (saw some holy priests in icc gear with 30k in dala), 31-point talent trees and only 41 points (no more 15% str boost for palas /cry). Some nerfing to DKs, blood and frost presences have been interchanged. Blood is dedicated tank tree. alot more emphasis on Guild over friends list, now get in-game notifications when a guild member logs in or out (really annoying if your guild is big). Pretty much everything to do with Specialisation, Spells, resources etc. has been overhauled really, and ICC and RS lockouts have been screwed with. e.g. you can do a 10-man raid or first 4 bosses, then continue it with 25-players in the same week, from the point in which you left off in 10 man, and loot is apparently the same in both. some minor (but nothing huuge) nerfing to locks and hunters. Also, some 'Requires Level 81" spells are in game already, and a higher level of riding (310%) can be bought for 5k, ontop of the 5k for Artisan and the 1k for CWF.
basically class wise, Warlocks and Hunters get a little more OP, and Palas and DKs got nerfed into the cold hard ground.
POV Pala...
also, at this moment in time (about 60% of the final patch data downloaded) WoW takes up 28GB of hard drive space :/. And also, overlord, did you have crazy latencies on other PCs on your network while downloading? while main patch data downloaded (the 5.29GB stuff) it did about 10MB per half an hour, and the ping from other PCs on my network reached 5000ms.
