I honestly hate warlords. There's nothing new or interesting here.
Ouland again, Orcs again, Timetravel?!? Yawn. Jump the shark yawn.
Most classes have been pruned down to mind numbing 3 button rotations. Skills that existed for 10 years have been removed. Reforging is gone. Professions are meaningless. Garrisons and followers are an ipad like minigame glued into Wow. All they needed to do is sell garrison resources for cash to make a standalone freemium game. Don't like battle pets? Well, too bad... now you have followers that are just as bad, and mandatory. And don't get me started on how little sense it makes to have everyone sitting in their instanced garrison and obsessing over it in an MMO.
This expansion is 100% nostalgia. Which is why it's boring. Now if it had been "Warcraft: Return of the Titans", that I'd have been excited about.
That said, I expect this expansion to be hugely successful. Wow players have proven they don't like anything different. It's always been about Orcs and Humans to them. And there's nothing really wrong with that. Meanwhile, I'll be working on my Steam backlog.
