Engineers! What are some viable playstyles?

I'm finding I use the rifle most often... I like blasting enemies away. :)

Me too, but it's not so much fun when it knocks me down at the same time :) Shield blast does the same in aoe, and has an anti-ranged alternative. Far superior to rifle imho.

Dual pistol and elixir gun were my choices. I just liked them (rifle was fun too). I have no clue what was best...
