The CQB nature of Gears, with its gnasher combat, makes it somewhat unique… every other game (CoD, PuBG, Apex, etc) seems to be about killing people from far away, with a quick burst of a rifle like weapon.
They can’t make Gears to be like that without completely destroying the franchise: it will be a different game, just under a Gears name.
They can’t Gears notGearsy enough to make it appeal to CoD people but they CAN make it nonGearsy enough to lose Gears fans (which is what G5 is doing).
So all downside, no upside.
