Whining about it won't change anything. Besides, given all the bad press Galaxies received, I think we can infer that BioWare won't make the same mistake Sony did. They're using a different game engine anyway, and personally, I'm hoping for the D&D Online engine. That'd work well. The WoW engine is, of course, a tried and true favorite. Largely, the question for me is just gameplay.
And this doesn't necessarily mean that story has to go totally out the window. D&D Online, for example, uses purely instanced dungeons, so you still feel like you're an isolated single-player, and Pirates of the Caribbean Online manages to pull off a decent incorporation of an actual main story. Let's not complain until we've seen the thing.
