I do recall him saying something about only having seconds to catch the attention of a potential new player, and that they purposely left the melee OP for the game’s launch to showcase it but I dont recall this exscuse being used for anything else.
I wont deny that plenty of the core elements of the game has been changed with the sole purpose of attracting casuals and reducing movement speed may have been one of those, but I honestly believe that the speed was reduced due to technical limitations.
Just look at the state of the game now, it’s not just the gnasher, plenty of weapons now outright “miss” your opponent (bullets/pellets go through them), I dont think it was a coincidence this started happening with the movement update.
Unless their code base is tightly coupled spaghetti (I doubt it, but you never know) theres no logical reason why changing some values to character movement speed would break a lot of weapons in the game UNLESS the core networking component completely breaks because of it.
