This is one of the biggest problems. Lock outs need to be tweaked in some way. It’s the root of all the issues here. I’ve never personally understood them, anyway. Who cares if people just want to spam a raid over and over? Why does it matter if they all gear up to BiS in a day? Timegating is just artificial content creation.
Add a pvp gear grind if you want to add elongated content for sweats.
