See what I mean? This is why you should play the game blind.
All this stuff everyone's talking about...none of it matters. Ultimately, none of it is necessary to beat the game. Don't listen to people who say you shouldn't multiclass or that you should dual-class everyone. I've played all these games multiple times and I always play a few multiclass characters and have never once dual-classed anything...and I have zero issues beating any of these games. You do not need to do any of this. Anyone who tells you otherwise is full of crap.
Roll up the party you want to play and have some fun. We all played it blind back when the games were new, and not knowing some of these things people are talking about won't destroy the experience one bit.
Honestly, this is how to play *any* game. Have fun, experiment, fail, try again, etc. Then *maybe* if you're stuck with something for days (not minutes, not hours, not an afternoon, at least *days*), then *maybe* try to ask for help. But usually that just spoils the fun, and it's better to wait a few weeks before searching for solutions.
