An imbalance of "overpowered" weapons can only negatively effects PvP play. Fun fact; every gun [i]ever[/i] released will [i]always be usable in the Crucible[/i]. Your whole point about balancing weapons becoming "exponentially" harder? Keeping current gear capped at 365 [i]does nothing to fix that issue[/i]; they're still gonna need to balance them! :P It only hurts PvE players, whereas letting players continue to utilize their favorite gear has literally [i]zero[/i] negative effect, on anyone.
