Wassup guys! So I was wondering if dex engi was good. Few days ago, I played with my 20 engi. And I decided to play things differently, so I maxed my dex. It turned out pretty good. First, I use suppression to stun my opponent from the wall, then I run and kite a lot until I successfully wasted my opponent's blur(mostly fought operatives). After that, I go bursty-kitey mode and deal tons of damage to them. And that's how I fixed my kd to positive. It also worked against commandos but you don't need to kite that much.
I might not be the first one to use dex engi. But feel free to try this tactic out and tell me your results And if you have tried this out before, please give me some feedback to how it worked out. It might not work great for you, but it sure did for me. Thank you all, I'll see you soon in game :P
