:/ Hate to be the downer, but it looks like a pretty solid take on standard MMO combat, which is not an insult, but not a compliment either.
My biggest complaint is the 2-3 second command input. What makes GW2 tolerable is that you can slam your command buttons really fast. 2-3 seconds between inputting a command is exactly enough time to be boring and exactly NOT enough time to do anything else, like talk to another player. It's fine if they miraculously make it some highly strategic game where that time is spent figuring out your next move, but I'm 99% confident that this won't be the case.
So again, I'd really like to be able to queue up 3 or 4 attacks (and to be able to change what I queued). Then when I am fighting something boring, I can at least talk to other people.
for a game like this, i think a moderate queue system would be appropriate and fun. what i like about gw2 is actually the fact that they DO have a small skill queue mechanic. just enough to keep a second ahead of the action. you can basically queue one move ahead of yourself. swtor has a similar mechanic (that you can actually adjust the timing of....why is this feature not in all mmos?)
and speaking of auto attack...its kind of funny how mmo combat has become faster and faster paced, rendering auto attack mostly meaningless (the whole point of autoattack, i assume, was to make it easy to chat during battle...but mmo combat is generally so fast paced nowadays, you cant chat much in battle anyway, AA or no AA) its really kind of a dinosaur mechanic imo. i see why games like GW2 still use it (facilitates better more consistent dps....which i think is silly for a number of reasons)
at any rate, i'm glad to see less of an emphasis on AA in this footage. i'd be sad that they are sticking with the ancient MMO combat style of standing in one spot beating on the mob, but i already knew that was going to be the case. tbh, after all this analysis, im starting to realize that, maybe the quality of combat in this game isnt as important to me as i thought it was. just like XI, i suspect it will be the game world and people in it that decide the fate of my sub fee.
