I’m most likely the resident WoW guy in strats. The next expansion looks like it’ll be summer or early fall 2018. Even if people want to roll some new characters before the expansion hits, I’d be for that as well. The next update 7.3.5 is gonna be changing things quite a bit, with the leveling experience from 1-100 changing to a pseudo-scaling (like Westfall will be 1-40 instead of 10-15 and Outlands & Northrend will be 60-80 instead of 58-68 and 68-78 respectively).
There’s also a pretty popular movement going on called Project60/70/80, where people are trying to capture the magic of Vanilla/BC/Wrath before WoW Classic servers are released. That could be some casual laidback fun (the rules are pretty serious, no dungeon finder, dungeons/raids with only guildies, no leveling gear allowed, etc.).
