*Sigh* Because you don't have a choice in loadout once you have this almighty boon. I complete end game for several reasons: - the raid weapons are really great under certain circumstances, so collecting them for my arsenal is fun. - the challenge is fun. - playing with friends is fun. - getting all the raid weapons is fun. - they're releasing harder and harder content, (exhibit A: challenge raids) so I need to gear up for them. - maxing out my character is fun. - some of the weapons are great, but not "the best", like the machine gun, pulse, scout, sniper and shotgun. - infusion material for my other weapons, that AREN'T unbalanced. With the freedom of choice, you can use whichever loadout that you're personally happy with in both PvP and PvE as opposed to what universally considered "the bestest one evar!!" And variety.
