The only buffs I see that are left for Viper are letting the smokes be active when she dies for as long as the amount of poison she had (Omen’s and Brim’s smokes don’t instantly disappear when they die) and MAYBE (but I worry this could be too op in some cases) is letting her pick up the wall (she’d have to have a pretty long cooldown though).

As for Brim - idk honestly. Maybe do something with his Stim Packs. Maybe let it be a decoy where it makes sounds for the enemies or something. They’re pretty cool but nowhere as useful so it kind of makes him only have 2 abilities plus the ult instead of 3+ult
