You also only saw the lightsabers lock up in combat if you ONLY auto-attacked in every single fight. If you used any other abilities instead you would use an attack animation that the enemies never interacted with and vice versa. It's nice, but why waste the resources on it if it's not going to be used much?
You really don't use basic attacks much? Like 90%+ of the animations that proc when I play are basic combat animations, and I like it that way. I don't waste most abilities on single small enemies, and usually boss and up enemies survive long enough to get into some level of a basic combat attrition duel. The only combat encounters that don't see a good bit of it are small, clustered, trash mobs, just because of numbers and aoe. So if the vast majority of what I'm looking at (if encounters are strong) is basic combat, I'd really like for that to be as interesting as possible, not just repeating chains that always connect. Honestly the DA2 style attack chains are boring. At that point, you may as well remove cooldowns all together and have endless special moves, if that's functionally how you intend it to be played, because you're not involved with to-hit, dodge, rolling crits, etc. You turn it into an action game with strategy and character building elements instead of a tactical rpg. I want a beautiful rpg that looks like an Arkham quality action game with a strong battlefield tactics system like we see here so far, not an actual Arpg.
Those animations in KoTOR weren't few and far between like that little video. They were the sinew of basic combat, and there was a lot of variation to it. They were context sensitive. Imagine what we could have if they were to embrace that idea with today's capability. I know it requires some work like every other aspect of the next game will, but it's not that far removed from what we have now. KoTOR had the same special move interrupts and party combat we have in Dragon Age. There are already turn-based systems built into DA. I'm requesting it now like I did when DA2 came out. It'd represent a major improvement on everything they're already doing right this time out, which is a lot.
