Just read the article, and I particularly agree with 1, 4 and 5.
1)The Mass Effect trilogy is supposed to be "Shepard's story". This whole Galaxy at War thing detracts from it. Sure it's a war, and other people are fighting on other fronts. But that should be material for other games. Games that don't focus on Shepard.
How much Shepard-centric content had to be cut/downgraded to DLC sue to space contraints of fitting both single player and multiplayer to one game?
4) This is exactly why I'm done with Mass Effect after 3, and I'm not even guaranteeing I'll get it new (why should I pay for an online pass I'm not going to use?), why the Dragon Age 3 rumor has me
very nervous about that franchise as well, and why i'm taking a long, hard look at any Bioware product to be announced from now on. It may be too late to change ME3, but that just means I'll take my money elsewhere. Why should I pay full price for only 3/4 of a game?
5) Indeed, this means that either a) The entire War Asset system will be a trivial aspect of the game

Gaining sufficient War Assets in the single player game will be extra difficul, since you're "supposed' to be doing multiplayer as well or c) Gaining War Assets in single player will be a challenge, but multiplayer will make it an almost nonissue.
I know, I know, War Assets are only a part of the whole galactic war thing. But gaining a tech expert was only a part of the Suicide Mission too. But you get someone killed if you don't have one.
