You say "Most other MMOs [do what WoW does but better]" and then go on a rant about Blizzard stealing ideas from itself instead of substantiating the claim.
OK, fair enough. For example, a game that's come after Lord of The Rings Online, does the same thing in terms of basic animation, but actually breaks few molds. However, LoTRO pretty much keeps the attack skills as powers, although, each and every one has a separate animation.
For example, they have a Plate Wearer that's built as PURE DPS, not a Tank, like the WoW Warrior was originally, which was a hold over from EverQuest. Which Blizzard had said they were going to change, but didn't until the 2.x.x patch series. Oh, the LoTRO class is called the 'Champion'.
As does a relatively new game called Aion, with the Gladiator. And that game feels a LOT more like WoW, but even it has a lot better graphics and a new plane for PvP combat. Aerial. You can FLY in that game.
If you want for something different, then let's look at Dungeon and Dragons Online, the combat is actually interactive. You click your left mouse button to swing your weapon up to 4 separate swings (If you're a Fighter) and it was #3 on the charts for 2009 (And it's an AMERICAN Free To Play game, that does a smart thing with it's Micro Transactions. See anything you can buy off their market, you can get in game for free, as long as you're willing to play for it.)
Thing is as for WoW, in the beginning, it pretty much hewed as close as it could to the EverQuest game model, with it's classes, much to the disappointment to some of it's fanbase. But we kept soldiering hoping to see if Blizz would finally implement some of their changes for some of the Classes (Namely the Paladin and the Warrior) it took a while but they did.
Alright, back to backing off. I'll come back if someone has a counterpoint to make that doesn't also have a chip on their shoulder about WoW. :p
I have nothing against WoW. In fact, I have Cata coming (As a gift) and a friend renewed my sub before I could get my income tax return to pay for about 6 months.
I LIKE WoW, but I'm under NO illusions as to what it is, nor how it does it.
