Gonna fail. When it comes to the meta of tanking healing dps roles if said mmorpgs do open classes they fail. The games that fail end up changing these ideas back to that meta. GW2 ESO Champions online and many others fail unless they make that change which some do but some don't like champions and it just closes.
In an interview, Npixel shared how their upcoming MMORPG Chrono Odyssey aims to redefine the genre by focusing on player freedom, innovative time-based mechanics and a flexible class system. A closed beta is scheduled for June with the full release expected in 2025.
