Right, I can definitely understand where the disappointment is coming from, and I agree with all your points on Mass Effect.
The reason I'm still remaining cautiously optimistic though is because when I looked through everything in the demo, the only thing that really stuck out as questionable to me* was the comically easy difficulty, because it meant I wasn't required to use any strategy or tactics to actually play the game. Outside of that, it still had a robust inventory, lots of stats, lots of skills, a surprisingly deep gambit system, and lots of cross class combo abilities and tactical possibilities in general that seemed like they could be interesting if I wasn't killing enemies in one to two seconds.
However, given that Normal is supposed to be a mode for people who only play one character, and we couldn't see the two difficulty modes made for parties, I'm willing to wait and see how that pans out when I play the final game before assuming the worst. I mean, even that German PC gaming magazine that gave the game an 87 rated the combat 10/10, and given the score it didn't strike me as an exclusive review, so I'm maintaining some hope.
