I heard on the AoC discord that expansions races and classes were specifically NOT planned. I can’t find verification of this, but if it’s true that’s disappointing.
It would be a real shame to not see at least Monk and Druid added at some point. I know it’s a daunting task since adding another archetype increases the class load significantly.
My advice is that it can still be done in chunks. You could release Monk + Monk and Druid + Druid first and slowly add in the other mixes over time. No one is demanding they release every combination at once. I think it would be a great way for fresh new class content to continually drop, too.
My two all-time favorite fantasy classes aren’t in the game. But I know I’m only one person with one opinion
