From my perspective it is a team wasted. Elves are still bugged. It does not help when they advertise new ways to spend your real money and provide content for it, while the singleplayer suffers.
Well, from mine, its not as I find multi quite enjoyable to kick around as do many people so ;p
But again, different team with a different development cycle. There's no reason the multiplayer team should delay the release of their work because the single player team screwed something up. Plus the multiplayer team is not working with the modular PC meshes or with the cutscene mode that are the problem in the single player game. So even if you did uproot them from their own work and forced them to work on the main game they might not actually be of much help.
Besides, I highly doubt the issue is just a simple lack of resources on Bioware's end. It could be a lack of time ( due to management decisions or EA breathing down their necks ) or a lack of experience with the new engine or simply having to beat said new engine into doing what they want to begin with. The Frostbite engine is not an RPG engine, it was made to be an FPS engine, so a lot of DA:I still had to be built from the ground up.
Then throw in the looming holiday season.
