The only thing I blame EA for is forcing more action-y appeal on Mass Effect. I wouldn't believe for a second that it was mainly Bioware's decision when they began ME2 to make it a Gears clone. It's something EA forced and another thing is that a lot of the new staff at Bioware are ex-in-house EA developers or from subdivisions of EA formed by EA, and have seemingly a more "game is about cool gameplay and guns" mantra to them. I'm totally prejudiced here, but that's my honest impression.
But still, mostly every other creative element, especially the story is 100% Bioware's to fiddle with. The only reason their stories suffer more in this EA era is because story is relegated to what the budget can do, and since they need to appeal to the morons with their cool setpieces and action gameplay they need to spend way more money on cinematics and action-y, level-based gameplay. If the end product is like a great action-movie in video game form then, hey, I can't complain, but more often not since ME2 we end up with story inconsistencies because the budget is more focused on creating the setpieces and gameplay than building a game around a plot first and foremost -- which is how every Bioware game before Mass Effect 2 or DA2 or any EA-Bioware game was built.
I guess my logic is: Yes, Bioware has changed a lot, but hey, if you think either ME2, ME3, DA2 or DA:I are good games, then you don't have any reason to blame EA for whatever faults ME:A may have. Instead the skepticism I have lies with the fact that Bioware Montreal hasn't proven themselves as a B-Team to create full games on par with A-team games (A-team = Edmonton). Again, the most recent change here is not anything with EA, it's with Bioware itself.
