You don't even need to really misplay, the dice can just screw you. At a table with a GM you can get inventive and try some crazy stuff ( and the GM there doesn't really want a TPK) , but as a game those things are less apparent and less fun. The game is incredibly cheesable.

Take all the talents you want, spend all the time you like planning your build, it'll never be better than tossing an explosive barrel down and just shooting it (for instance). And yet that's not fun for me, it feels like I'm cheating and not engaging with the game genuinely. But what else is there? The goblin camp is a slow slog and every time I see if done without cheesing it comes down to hiding away in a corner, building up your defenses and just slowly whittling them down and hoping they don't out roll you. (don't forget there's nothing bad about going down in 5e, since there's no lasting effects, just get back up, chug a potion and carry on.)

I love the game for the effort that was put in, but the characters don't call to me the way they call to others, and the game's combat seems hell bent on wasting my time and being unsatisfactory.

It's absolutely a great game, but I'd rather play with the Divinity: Original Sin 2 combat system.
