1. MP combos are not always reliable -- enemies evade a lot -- but they're certainly possible. I use them a lot with my asari Adepts. And it's possible to combo with other players too. One of my favorite times in MP was when I was coordinating my plain asari Adept with another player's asari Justicar adept; with my Warp/Throw and her Reave/Pull, we were setting up biotic explosions every couple of seconds. At the end of the match, we were about tied for high score, and we both scored about 50% higher than the #3 player...

2. Shockwave isn't super-useful, but it's sometimes handy. You can use it to detonate things, and if you get the Lifting Shockwave evolution it can also be detonated by other biotic powers. It can be an okay damage-dealing power if you get the range and width upgrades; because it can cover a really large area, you can fire it through smoke and have a good chance of hitting the enemies beyond. It can stagger Guardians, too, which opens them up for shots unobstructed by their shields.

3. I don't know of a way to make the announcer be quiet.

4. The different races/classes do have different heavy melee attacks; some of them do different amounts of damage and take different amounts of time than others. The batarians, for example, have a very high-damage, slow heavy melee. I don't know if there's any difference in the light melees.

5. I don't know any, although I have a few conventions I try to follow -- when I'm an Infiltrator I consider myself on task for reviving people, since I can slip in easily under cloak. In a pinch, I go after enable/disable nodes solo as well, since my cloak lasts just long enough to do them. I also prefer to let whoever can soak up the most damage carry the object on retrievals. One thing I *wish* people would do is use their microphones more -- missions go so much more easily when the players coordinate as a team.

6. I alternate between Engineers, Adepts, and Infiltrators. The Engineer (especially the geth one) is an excellent powers-based damage dealer, can also provide crowd control if you take the Neural Shock upgrade on Overload and at least one of the chain evolutions, and doesn't close coordination with other players to reach its full potential. I like to play an Engineer when I'm in some random game with people I don't know. The Adept, on the other hand, can provide ridiculous amounts of damage from powers, but needs another biotic with a complementary power set to really shine. I like to play an Adept when I'm playing with a friend who I can count on to coordinate with me. Finally, I recently got the N7 Valiant, which has really made playing an Infiltrator more fun -- Infiltrator is already a versatile class that can fill the utility roles on the team, but the Valiant makes it easier for me to be a damage dealer when I'm not reviving people or securing objectives, and makes the class much more fun overall.
