WoW: Forever: What's New and What Feels Familiar
Blizzard's explainer for modern and Classic players covers the two Experience Presets, Classic and Enhanced, which change presentation (quest guidance, one-bag view, transmog, HD models, layout) but not your Ruleset, plus Advanced options like the Cooldown Manager and a Damage Meter. It notes gamepad support is in a beta state, the level cap stays at 60 across Eastern Kingdoms and Kalimdor, nine new five-player dungeons span levels 13 to 60, and the new Skyborne race starts on Zephras Isle as Horde Windshaper or Alliance High Order Skyborne. Classes are revisited with talents rooted in original WoW.
