to those that tried it and didnt like it id say give it a lil more time, i hated it when i first came back as well, gameplay had changed, didnt know WTF i was doing and all that coupled with new zone didnt help, however i found that once you get through that initial block its quite enjoyable, havent hit 90 yet but running around questing is actually fun, new stuff is fun and interesting and all that
I actually don't mind the gameplay changes at all. I do have a few complaints about how some things have become trivialized (like glyphs), but there are some benefits (having Shadowstep as a Combat Rogue). I just don't seem to have a desire to play anymore. Part of my annoyance might have been related to how boring some of the starting quests are. For example, I had to do a vehicle quest, which
could be awesome, but it's marred with the fact that the game provides you almost no control over the vehicle except for aiming the turret. How boring! I came from playing Borderlands 2 where I get to drive around like a maniac and shooting the crap out of everything. That's like going from a crazy roller coaster to the goddamn teacup ride! :|
they call it phasing, and its annoying as fuck IMO, stuff will just randomly vanish on you because you havent done certian quest chains, really screws up farming for herbs/ore
I'm not sure if you've experienced it much, but Blizzard fixed phasing + gathering issues
a lot throughout Cataclysm. Unfortunately, the issues were almost always on a case-by-case basis, which means they'll probably crop up
again in Mists. It definitely was annoying though.
Unless something changed, the biggest problem with phasing is that there's no way to enter an older phase, which means you cannot help out someone... even if you're in a group with them. I'm not entirely certain that it's really that possible given how much can change between phases. With Wrath, phasing was mostly just placed units which includes NPCs and objects (trees, etc.), but in Cataclysm, this changed as now land was able to change. We saw this
heavily in the new starting zones. Unfortunately, without knowing how Blizzard implemented this, I can't really surmise whether it's possible to randomly join different phases to help people.
