I'm okay with it for the same reason that I can play and enjoy Halo; I'm not overly attached to individual weapons. I mean sure, I like the Fuel Rod Cannon, but once I run out of ammo with it I'll put it down and start using something else. So yeah, I've enjoyed using the current-gen exotics, but will I feel particularly sombre over them being phased out? No. I'll just find something else to enjoy. Where's the fun in using the same damn guns day to day anyway? The benefit of loot-driven games is the constant variety. Why ruin that by clinging to three guns?
