That is the kind of myth and misinformation that leaves most of the roster sadly neglected. Although there are some disparities in character usefulness that could potentially be recalibrated, the greater issues here are ignorance and the effects of peer pressure amongst the playerbase.
Are you speaking of Del, controlling the whole flow of the match with Fabrications, contributing to kills as much or as little as desired?
Or did you mean Fahz, vaporising Drones and the like with his Longshot before others can even acquire a target?
You could be referring to Keegan. Highly destructive and dominant with a set of Bleeding explosives.
I just feel like people are missing out on an awful lot by not giving any thought to the majority of the characters. Whether they’ve even explored this personally, or are just going by what others have told them, I’m not sure.
