>ME1
Every class is viable, Sentinel/Infiltrator is the easiest
>ME2
Biotics are fucked bigly, Soldier is the best thanks to Adrenaline Rush + Mattock/Revenant memes, you're better than the Infiltrator in every way possible
If you're a Biotic you must complete Kasumi's mission immediately to unlock the Hornet since it's the best gun you'll ever have until you get the Claymore
>ME3
All classes are viable again but Soldier is still the best now with Garrus and James with the N7 Typhoon
If you're playing Engineer Insanity in ME3, Marauders and Banshees ignore your AI bots and target (You) or your squadmates
In ME2 and ME3 you should never get out of cover while in a firefight, turn auto-powers off and you have to micro your squadmates because they'll be instant toast and die fast.
Kaidan/Liara/Wrex are the best teammates in ME1 while Miranda/Garrus/Jack are your best buttbuddies in ME2.
For ME3 it's Garrus and James with the N7 Typhoon, watch them clear the map and never micro them on Insanity.
Infiltrators fall off a cliff in ME2 and ME3 due to the Soldier being absolute bonkers with Adrenaline Rush, there's no real point picking the class and you're stuck with the basic bitch M-92 Mantis until you can switch to the M-97 Viper on Thane's mission or the Widow in the Collector Base.
