Actually, come to think of it, not only can I wasd in WoW, and map all of my mouse, should I choose, or use move-to-cursor two-mouse button, I can also use my arrow keys to move (both the ones on my keyboard and the ones on my numlock)--and all without remapping. I can go forwards with my w key and backwards with my down arrow, and then switch to s immediately. And then immediately move forward using my mouse only (while I take a mouthful of the coffee in my left hand), and then I can immediately left-click attack and mouse click my action bar, put my coffee down, and then use a hotkey to Bestial Wrath, then strafe using my mouse movement and hotkeys when their CDs have finished. Oh, and "backwards" means just that. I back up. I don't turn around and run the other way.
Also, a and d are literal sideways movements--left and right respectively. If I want to strafe I use q and e and/or move-to-cursor.
With the arrow keys near my right hand and my hotkeys being used by my left and right hands, I could actually play WoW without a mouse, if I wanted. And with their mouse support and remapping and enough mouse buttons, I can play without hotkeys.
All of those different methods of movement/attack are available to me, in WoW, simultaneously.
And if I don't like any of it? I just remap everything. Like, everything. I can attack using my delete and esc keys if I wanted. I don't. That's an example. But I could. My son--whose play style is very different to mine--uses mouse movement exclusively and has almost his entire keyboard mapped to macro hotkeying. It's so different to mine that logging into his char to check his mail (his Main is still on my account and he no longer lives with me) sometimes has me accidentally charge the nearest wall instead of opening the mailbox. Heh. Yeah, I don't play warrs on WoW, even if they're my favourite DA class... but I digress. I think his mapping is insane, but that's HIS char, so HIS choice. DA:I took all choices away.
WoW is all very efficient, really. And DA:O had similar mouse and keyboard mapping and support.
DA:I wasd is just like current MMOS. Snort. If anything, the comparison shows -- even more -- how clunky and awful DA:I's KB&M is.
Seriously, I just played an archer in DA:I. I would have loved to back up occasionally instead of turning all the way around just because I hit s. And don't even get me started on melee. In WoW, I don't have to worry about my DK standing there doing nothing like a diseased lummox just because I have to reposition her or the enemy took a step sideways (but, y'know, is still within reach), or my Kittehdruid going "hey, taking a nap now, because that guy moved". You have to literally turn your back on an enemy to not attack it if it's still within range. Because, yay, autoattack.
If they were trying to emulate MMOs (a PC-oriented genre, btw), they did a horrible job of it.
