If you can get a Salarian Infiltrator, you have a devastating class. Just max out every skill (except Proximity Mine, dont put points on it), and you can drain shields while in cloak, then fire shots and finish off even the toughest infantry. He can even single-handedly take out Atlases and Geth Primes even on Gold.

The Human Engineer I think is overlooked quite a lot. They can use Overload to destroy any enemies shielding, failing that, it deals significant damage to them. Then after that, since I've forgone Combat Drone to get Incinerate, I can then burn armor, Health, or even shields if need be or multiple enemies at once. I can inflict so much damage to any opponent like this and I carry a Tempest and M-6 Carnifex and I still have a 185% recharge speed.

I've also been using Krogan Soldiers recently, and I maxed out all possible melee damage upgrades, couple it with a Strength Enhancer III, and good god, I was laughing like a hyena! You can easily melee the living crap out of almost any foe. On Gold, one Heavy Melee eliminates Assault Troopers, when purging fortification with 100% extra melee damage and rage on, you can eliminate Nemeses in one heavy melee, Centurions are downed to half health and no shields, and Phantoms are killed in two heavy melees.

Good times :D
