I think that Proxy and Fletcher are long overdue for a rework.
Both are too offensive for Engineers. Proxy is terrible at range. Fletcher is disgusting.
I think that their abilities need to be reworked or given to characters with different weapons. A landmine (that can’t be used as a grenade) would be more sensible with a character that has better weaponry, like a sniper. Fletcher seems more suitable as an agent with buffed health, as he would not need sticky bombs to be good at range anymore, thus allowing a nerf to make them proper defensive tools.
Yes, getting rid of Fletcher’s shogtuns for magnum secondaries could ironically make him better. That’s how valuable shotguns are on engineers. You can’t engage at medium range with them, which is extremely meaningful because even a competent Blishlock player (all headshots) can shred 110-140 HP characters in 0.6 seconds, while landing a second shot on a shotgun takes 0.63 seconds at best.
In order for a glass cannon shotgun engineer to be both useful and fair, that engineer basically needs abilities that buy 10 seconds of time per use (like Rhino), and can’t be used in an offensive manner. Or, the engineer needs to become a giant counterspell to the biggest threats to a defensive formation: explosives.
I mean otherwise, we just get a big fat load of ehh when trying to make characters that have their combat abilities be focused on defense, and have to put up with using a shotgun.
