Why is endgame loot capped?

Also I love how there's so many replies who don't even bother explaining the actual reason. They just say "it's normal", or "other MMOs do it too".

No see, that's the real juicy bit to me, they are saying that seemly without realizing that every MMO that does it, does it for the same reason, no game want to lose players, even f2p games needs their free players so that their paying players have people to play with.

Just because an issue became standard doesn't mean it isn't an issue.
