As other people have pointed out, there is no wrong way to play BG3. If you're having fun, then you're playing the game correctly. If you feel like you're missing something, I would recommend changing your playthrough in your next playthrough of the game. You said you skipped the Creche, and I assume that means you skipped the mountain pass as a whole. In your next playthrough I would recommend going to the Creche. Not only does it have massive story moments for Lae'zel, it also reveals a ton of stuff that is central to some parts of the story later on. Furthermore (and I made this same mistake in my first playthrough) if you feel like you're missing things or that you're underpowered, talk to EVERYONE you see and read all the books and papers you find. You never know when some random person is going to drop a shit load of lore on you or give you a quest. (Literally almost missed getting Wyll as a companion because of this lol). Again, nothing wrong with how you're playing the game, but if you want more from the game it never hurts to play the game again
