@ Crni Vuk: Well, as I said, FF means you have to be lots more careful (possibly the Rain o' Arrows would have damaged the guys in melee and changed the fight).
And anyway, choosing the right spell and using them the right way + positioning my guys correctly = tactics, imo. In anything that isn't an RTS or a cooperative multiplayer effort (WoW, for instance), you can hardly get more elaborate tactics from players in a game (feel free to prove me wrong; I would love to play a game that goes deeper in tactics, and yes I did play Jagged Alliance).
Of course, you can counter this by having enemies that do more than run up to you mindlessly or cast random spells (and sadly the enemies in the video did just that). The more elaborate encounters are always the most fun (I found the dragon encounters and such in Origins very nice because they broke the mold, so to speak). Problem is those encounters are frequently spoilerish, so they cannot show them in promotional videos if they have them, even if there's little doubt there's going to be a dragon fight somewhere.
Also, who used cover in ME1? On my Vanguard all I did was to use Immunity while my enemies did too, making fights about 30 seconds of endlessly shooting at somebody, rinse and repeat. When I got tired, I just Lift the whole room and lulz ensued. Charging around in ME2 was so much more hectic and fun. You very much have a point; hybrid systems can suck very easily.
And finally, I would not put much trust in any marketing campaign made by EA for Bioware. Origin's was all about action and blood and jumpy shit trailers and *shudders* Marilyn Manson. I found the final product much more tasteful overall; maybe it's the same thing here. I am still happy they actually did the video in the first place; it cleared some things up and calmed the endless shit-storms in the official forums a bit.
