Either a player likes the crunchy rules or they like super-lightweight freeform play. Finding a group of people who like both when that Venn diagram is effectively two separate circles is going to be hard.
That is 100%
not my personal experience.
Like, my main group, they've played everything from Rolemaster to Cortex Plus, and they went directly from enjoying 4E D&D, which is perhaps the second-crunchiest edition of D&D after 3.XE, and the most gamist edition by far, to enjoying Dungeon World, which is a very rules-light PtbA game. More recently, we've been playing Mothership (incredibly rules-light) and 5E (which is, by modern standards, rules-heavy), and even min-maxiest player, a reformed munchkin even, clearly has a great time in both.
Also, finding players that I feel will work well for it might be a challenge, because I don't think any of my current players are the right fit. Maybe one of them, but not sure.
I dunno. See above I guess, maybe I'm #blessed but I genuinely don't think most players have a strong preference for crunchy vs. light if they've actually played both for more than a couple of sessions. And that applies to people new to RPGs too in my experience. Hell, if anything, different RPGs can bring out different things in people. Like, when we started on 4E, suddenly one of the players who'd never been interested in optimization before, got interested and had a great time, and when we started on Dungeon World, the guy who we always saw as mostly a min-maxer pulled out some great role-playing that we didn't know was in him!
Daggerheart has nowhere near the crunch of D&D though. It's classes have, what, 4 abilities?
You have up to five Domain cards (like spells/active abilities) at once, plus maybe few basic class and subclass abilities, two racial abilities (often just passive modifiers) and so on. That said, some of the mechanics are not simple-simple, I'd say it's solidly in medium crunch, like, significantly crunchier than anything PtbA I've ever seen
except from the Sons of Oak guys (i.e. City of Mists, :Otherscape etc.), crunchier than Spire/Heart, but enough less crunchy than 5E that it's clearly not in the same ballpark (even if some of the same ideas re: optimization may occur).
