Yes. There are a lot of ways to exploit the game. No doubt. What concerns me so much about the stealth mechanic, though, above all others is that it can be easily discovered by brand new players who know virtually nothing about D&D or the game or anything.
It's kinda an RPG staple to sneak. So even players who are brand new will do it as soon as they find out how. Then, when they learn you can shoot and stealth in the same turn, and enemies won't even hunt for you... It's over.
So yes, I agree that barrels teleported through pockets is cheese and Minthara exploding with no response is not good, but those exploits are less easy to discover, so they aren't as big a deal to the game as this stealth problem.
This is literally a game breaking issue. New baby player stealths. Shoots. Stealths. Realizes this can work on just about every fight. All challenge is completely removed from the game until there is a fight that doesn't let them do this. By that time, the player has NO idea how to strategically fight anything because they've been stealthing it the whole time. Thus, they get stuck, frustrated, and quit the game thinking it's dumb. Either that or they quit long beforehand because of just how dull combat is
