I would really like to see a gate system. Have lockouts for new content for the first month or so, then open up as the patch goes on. So those who clear content will have that exclusivity for a bit, but then be able to help out those who are struggling with the content. It doesn't need to be six months or so between patches before we can play with our FC mates. Heck, I am still helping some guildies get through EX primals and T5. It would be nice to be able to help them while the content is current, but some exclusivity was had by having a gated system.
