I loved the original triolgy's combat too, but if you watched a demo of it, it probably looks pretty boring, like most great RPGS. I'm not saying Andromeda is as good or better, I haven't played it either, but this demo is definitely not how we should be judging it.
This "IGN First" thing is basically a company (like EA) getting in touch with IGN and saying "sell our game to your audience". I think this video does just that. As you said, the guy playing is terrible, and he's getting away with it since he's definitely playing on Normal difficulty or lower. He shows off some abilities but they all feel pointless, as anyone who's played a videogame before knows he could've progressed using only his right and left trigger. I don't think that will be the case on the highest difficulty. I'm dissapointed that squad controls have been simplified, but you can still trigger those 1-2 combos of abilities from previous games, and you can still tell them where to stand in combat, maybe that will be enough. We'll see.
I had such a great experience with the original trilogy, even if Andromeda ends up being terrible the series will have still more than justified what I've given to Bioware in return. Let's be honest, there's not much else to be that excited for until maybe Prey, so fuck it. All aboard the hype train.
