I personally dislike the monk class because it's ridiculous and immersion breaking. Any monk first and foremost is a person who dedicated all his life to the service of the deity. Therefore, the player must be obliged to do some stupid boring rituals most of the day. The correct way of allowing players to play monks will be to force them watch the cut scenes of praying for 5 min after every short and long rest, and force them to watch other stupid rituals monks suppose to be involved in, depending on their deity. Another thing is that monks should separate themselves from the rest of society unless they are providing a service favored by their deity, predominantly, it's a service of religious nature. Therefore, monks must be prohibited to get involved in the companion quests unless it fits and advances their deity values, romances of any sort must be prohibited too unless the monk serves a deity that promotes lust or spread of diseases (the monk then must be permanently infected: Typhoid Mary style).
This doesn't seem reasonable. Are you the actual enemy of fun?
I'm all for fun and also I'm for consistent universes: for content that make sense. If you insist that BS classes are fun then D&D must add machine-gunner class, alien class, space marine class, and whatever other non-fitting classes you can imagine. You're not against having fun, right? I'm pretty sure it will be fun for someone to exterminate goblins using minigun, Fallout style.
That being said, I'm pretty sure Larian will add this class as playable, I'm just stating my disposition towards this class in general, so, you'll get your wishes. I'm glad though there will be no party members that are jarring contradiction with the environment.
