Help me not be an idiot
See ranger coming or first/second arrow and hit your Shield 4 and laugh
The challenge of learning to play a 3 kit Engi, (I’m assuming you are new to Engi?) is staying alive long enough to learn which rotations to make, in which order, as different situations arise. If you aren’t really proficient with Nades (I’m not and I have 4,100 hours on Engi, lol), you might want to change them out for something else. Also, maybe drop Shield for another Pistol.
Also, maybe trait heavily in Alchemy and Inventions, and just try and survive long enough until you learn your rotations.
