Roles, in this suggestion, are defined/classified by the different types of abilities and their usage. For example, shaman would be support, barrage/dual wield would be assault, telekinesis and time warp would be utility.
With that in mind, as the title suggests, these separate groupings should be granted some sort of passive that can be utilized throughout gameplay. As I am neither a developer or a particularly active player anymore, the numbers and concepts below are purely arbitrary and were not made after deep consideration, and therefore are obviously prone to change/suggestions.
SUPPORTS: Health regen increased after avoiding damage for a period of time, revives dead players quicker(make it feature, not a once-was bug )
ASSAULTS: Damage or kills can count towards reducing ability cooldowns(this would likely scale “negatively” in order to balance itself out in later rounds). This puts dual wield in a weird spot, but beyond damage buffs it is largely an ability that can’t really have a passive buff regardless.
UTILITY: Placeholder, because I honestly have no idea what a beneficial passive that encompasses all that falls under this category would look like.
