It’s just an idea as of now…could be bad, could be good.
This new concept works like a damage mulitplier for heroes with similar skill sets.
For example
Using hivemind and halloway in the same team will activate their respective synergy, increasing damage done by their weapons and drones/Holograms.
Using Moss and Nightingale in the same team activates their synergy, increasing the sniper fire rate but reducing heal per second.
You get the idea!
And also, it’d be nice if they added a small icon showing the role of a hero, maybe below their faction, i.e, nightingale (below her faction) Role:Healer/Invisibility counter. The existing hero description doesn’t do much in terms of classifying them into their roles.
