So Over the weekend I made a thread in response to the Operation Goliath challenge for Mass Effect 3. Now I think, "Hmm, maybe it'd be good if just make a thread to help those having trouble with all the different types of enemies in the multiplayer." The ultimate goal I guess is that we as a community will eventually devise a way to get a full extraction on gold. Leave your advice, make sure to reply and discuss with other posters, and good luck. My own two cents so far has been use any combination of human or asari adepts, any sentinel and heavy weapon toting krogan soldiers against reapers, engineers and infiltrators against geth, and no matter what have an asari adept or vanguard against cerberus so they can shut down those damned phantoms.
