I played alot of OM and S&A. A LOOOOOT.
OM needs some changes for sure. He is surprising versatile for such a simple character. The way I had him build was optimized for taking out supports, buildings, and minions (apparently) Whereas other people have made builds making him the ultimate assassin. His base stats are fine, but some of his helix abilities need some tweaking.
Shayne and Aurox are my favourite though. There’s never a dull moment when I play S&A. I built them so I could negate a lot of a target’s shields by using fetch, repair my own, AND get overshield on top of that.
They aren’t broken, but their helix abilities could use tweaking as well. Nothing too major, but a slight change here and there would make a world of difference. Where exactly? Beats me!
TL;DR: I played a lot of Oscar Mike as well as Shayne & Aurox, and they do need a bit of a nerf. But only in regards to their Helix abilities. Their stats are fine as they are.
