Now that is a bit troubling. Taking away "meaningless" stats sound suspiciously like "we're taking away everything stat related". The thing is, they already mostly did that in Mass Effect 2. So..... what else could they take away? Accuracy stats? Already gone. Hit point stats? Pretty much gone as well - your HP just goes up with your character "rank" and level. Weapons stats? Again, ME2 already doesn't have that sort of stuff.
I've never been a very big fan of Stats and stuff, but taking it away would pretty much remove all sense of RPG. If you take away stats entirely and just have different "Classes", how is that much different than a COD load-out? I hope they're not going down that road.
Having said that - I haven't played Mass Effect 3. I'm not going to pass judgement on a game I haven't played. If they do remove stats entirely (and that's not what they said, but I have a suspicion that is what they are aiming for), they had better massively improve the shooting and character-action elements.
And combat mechanics are more or less directly separated from story mechanics. I have to be honest - I wasn't that much a fan of how ME1 played. I loved ME1 purely due to the story, universe, characters, choices and the feeling of immersion. In my opinion, ME1's combat was pretty awful (although towards the end of the game it became ridiculously easy - 2x Frictionless material X + Spectre Weapons + Soldier Class = always win at everything). ME2's combat was significantly better, but again, that's not why I played ME2 - I played it for the characters and the universe and the feeling of immersion.
So even if they mess up the combat and the combat mechanics and the levelling up mechanics and the loot mechanics and the invetory stuff - as long as they get the story right, that's all I really care about. I suffered gladly through ME1's atrocious controls and inventory system for its fantastic story. So long as they don't go "alpha-protocol-yeah-it's-broken" on us, I still think I'll enjoy Mass Effect 3.
