I think Zemos might be correct though, I don't think this is going to lead to Mass Effect getting further dumbed down. Fact from the looks of things ME 3 actually got meatier then ME 2 in terms of upgrades, and powers and skill slots. I think they want to make the game more accessible without alienating their fans.
You remember those stats they pulled showing that a majority of gamers play manshep on their first play through, or how most played the soldier class? Well they didn't make Shep a male or exclusively a soldier class did they? What the did do is say, "hey maybe we should give all the classes the ability to wield any weapon they want but limited the number weapons they could carry unless they were a soldier class."
