They aren't going to remove a lockout just to put in another one.

You guys got to remember that ilvl 90 in patch 2.2 will not be top tier anymore. It will be entry level gear for coil 6-9 which drops the new top tier gear. Most likly they will uncap mythlogy as well because they are adding a new tombstone which most likly you will buy the AF2 they showed off which will have the same ilvl as coil 6-9.

The reason they make the outdated ilvl 90 gear more accessable is they want casuals and new players to be able to catch up to current content in a shorter amount of time so they can experience the games new content. Creating a 3 month gear grind for old tiers doesn't make any sense. Because people have to have a catch up mechanism otherwise new players and semi casual players would just quit out of frustration.

1-5 having no lockout in 2.2 is no big deal because you got to remember, ilvl 90 in 2.2 is like the new darklight.
