New League & Past League Concurrent for Challenge Rewards?

Would it be awesome to have a new league as we do every 4 months to experience new content but also have the option to have a past league to have access to its challenge rewards and experience on a separate server?

I truly enjoy doing challenges as stressful as most of the time they are but its great to have obtain its unique rewards. I would love to have access to past leagues challenges.

...anyway, just a suggestion for consideration.

+1 access to past league server. but it should be void only and may come with a price tag.

-1 on challenge rewards. its timed exclusive to get people to play during that time period. if you let people be able to reearn past rewards, you take away the exclusivity away from all those players. which can make them feel bad.
