Lockouts: The game

[Sylve]

Because some people would end their subs once they had their fun and felt done to wait for the next content patch that is likely months away.

You mean, the same people who would spend a day running endless Coils for full i90 for every job, then unsub within the week if we didn't have lockouts... Lockouts are required to give meaning to gear not top tier. MMO's are about wasting time. If the game isn't wasting your time, it's not doing it right.
The trick is to be an entertaining waste of time. For me, XIV is that.

If all you want to do is the max level raids for the very best gear... go play a single player RPG, You'll likely get more entertainment value from it.
