Equalizer is top tier. Sidewinder is a fantastic backup if you need something lightweight.
Asari Adept like I said before. Vortex always for me. Melee recharges your shields faster and Vortex means you take less damage to begin with.
I can't agree on the weapons. They feel bad to use. I'm sure you could call them balanced because the game isn't impossibly hard or anything, but they're not any fun. Firing away all 50 or whatever bullets in your Charger at a nearby Overseer and then having to reload because you're not even through its shields feels bad. And then firing away 50 more bullets and it's still not dead. It's so bad. When it's usually not a good idea to use your gun if you have an opening to run up and punch, that's a problem.
As a common the Charger is still more effective than many uncommon and even rares from ME3 MP. I can remember being one of the few to ever use stuff like the Tempest, Phaeston and Locust in Gold/Plat. Charger feels OK for a common to me. I agree melee is a bit of an issue, but that's because of sustain. A quick burst of damage is fine. Being able to constantly punch to refill your shields is too much. This is one of the reasons I find the Krogan Vanguard to be the most fragile of them all.
I only tried a couple games using it but it seemed to give only a few points for damage/assists (as in +10 or so). I only have it ranked half way up so maybe that has to do with it? Perhaps you could elaborate on how it gets you points.
Place all of your points into Invasion first. Then all of your follow up points to anything that boosts Invasion with some points into Shield Boost as you like. How Invasion exactly works is a mystery locked behind wonky mechanics. Rank 4 I take Outbreak hoping it works, but others recommend Recharge Speed which will always work. Rank 5 is Epidemic for me, but another mystery in practice. Rank 6 is the important skill.
Virulence always. Virulence kills most small enemies outright when they get below 15% health. In groups it can trigger a chain reaction of kills.
Cast Invasion on targets with the highest health when possible. Also cast it on anything you can inside a large group so it starts spreading. Again no one really knows the details on how it spreads. I REALLY don't know the details on duration because it frequently outlasts my focus and the random kills are plentiful.
All of the regular weapons work, but my favorites are Falcon and Scorpion. As the Operator I try to cast Invasion on choke points and keep the enemy bottled up as much as possible. When Invasion starts popping Virulence the closer everyone is together the better. I'll frequently leave stragglers behind and move on to the next group because they'll die to virulence eventually. Won't steal as many kills when in a group of good snipers, but still performs well.
