Small review of the patch so far.
New Heroics - Extremely fun, they are not overly long, have some challenge, but don't feel too much like a wall. I would actually say they feel a bit easier then the troll heroics. The only thing that felt a bit strange is the difficulty curve. End Time actually feels more difficult then Well of Eternity, which felt a lot more difficult then Hour of Twilight, when it technically should have been the other way around. I hear the hardest boss of the new heroics is actually Sylvanas, who I didn't get to fight yesterday (End Time only has you fight two out of the four echos at random).
New Raid - Was unable to get a Raid Finder group going, but I heard the queues were having some issues, so I will have to review this later. From what I hear though the new "Tier" feels easier then Normal Firelands, but that many people feel the required item level for the difficulty is a bit high.
Transmogrification - My favorite part of the patch, I had collected a few gear sets, and they opened up a lot of my old favorite PVP sets from TBC (Just head to Area 52 to purchase them with honor). My only disappointment is they are not allowing us to use the lvl60 High Warlord/Grand Marshal gear with the system unless we have the Feat of Strength that shows we used to be of a higher rank in the original honor system, which I find really stupid. I hear they did it because old pvpers were complaining that everyone would get to use the sets and items. Same reason T3 is right now still missing. Still really stupid and old players need to get over it. ALL items should be open for this system if you ask me.
Void Storage - Meh, not really going to use it all that much. The cost for putting stuff in is a bit high (though, thankfully a lot cheaper then it used to be). I decided I am going to use it for items I may want to use for Transmogrification, but will not be part of my main Transmogrification sets. So for instance I made a great set on my Gnome Mage I will be keeping in my normal bank, but if I find another item that may be difficult to gain in the future, I will put it in the storage.
Darkmoon Isle - It has not appeared on Live yet, but I went there on the PTR. It is great fun with some cool rewards. Make sure you visit it at least once when it opens up next month just for the profession dailies and fun mini-games.
All-in-all, this is the best patch of the expansion and definitely gives me the same vibe as 3.3, which was when I played the most last year. It's really getting me back into leveling up a few of my alts I have ignored and maybe push up my tradeskills again. They still have not fixed a few underlying problems I have with the game, but I am hopeful those issues will be fixed with MoP.
