I stream 4 days a week playing tournaments with my guild Imperial. I have been playing engi for only about a week but I think I have picked it up pretty quickly and play it fairly effectively and I find it to be a lot of fun to play.
My build is a slight modification of Erho’s build who is also an amazing engi and I recommend checking out his stream as well for some great engi play.
