I disagree with removing gear lockouts or even content lockout. There is multiple ways to gear alts already. I feel Having those would provide more incentive to strive and play to get them. New BiS gear doesn't seem like a problem cause those are mainly for those who do hardcore raids. There will probably always be BiS gear no matter what gear system you have.

I do hope they put in a lot more new dungeons to do and plenty more other raids at the difficulty levels of extreme primals and coil without echo. This video explains how I feel about content https://www.youtube.com/watch?v=H9r34qSyYg0 and why I stayed and played wow for so much and for a long time from BC to WOTLK and for this game since 2.4, but they can improve on it for this expansion.
