Mmm. I’d say he’s a better Reaper. Hog at least has his hook. As for Reaper: Overload>wraith (perform similar functions, but overload has far more benefits). Turret>shadowstep (Obviously completely different. But if you had to pick one ability over the other…). Molten core>death blossom (area denial + dps. Except one destroys armor and doesn’t put the user in danger). Rivet gun>hellfire shotguns. Not only is the shotgun aspect better, but it has a long range option. Reaper does have life leach, but I believe everything else makes Torb better, as they serve a very similar role.
So I’d say that Reaper needs buffing to his shotgun to bring him up to speed. Keep shadowstep, but buff/tweak it. Given Reaper and Torb fill the same basic role, Reaper should keep his ability to more effectively flank. Then there’s a reason to pick one over the other instead of one of them just over shadowing the other in the same basic brawler role.
Same goes for Hog. Keep his ability to more effectively live at all times, but maybe give his Take a Breather added ability to help teammates around his radius (give them some hp or damage resistance or something?). Obviously his hook gives him different utility from Torb, unlike Reaper
