Odds are if you started World of Warcraft in the last few years, you may not have even seen several of the zones -- or entire expansions for that matter. Old content has long been a burden or a boon for MMOs, and when you're knee deep in six expansions, the prospect of starting one up can seem insurmountable.
Patch 7.3.5, which dropped earlier this month, changes that with a complete world overhaul, introducing level scaling into the mix. I talked to Paul Kubit (senior designer) and Shani Edwards (producer) about how the community has been taking to this shakeup.
