I appreciate the responses in this thread have been so nice -- my initial reaction was confusion to OP.
Why come to the BG3 forum to tell everyone that a level 1 caster is hard and that they refunded the game before really trying it? I get a truly antagonistic vibe and I don't think OP wanted to do anything constructive.
OP: it's alright you don't like the game. The D&D system isn't for everyone. And believe me, for people who play D&D on the regular (myself), they actually made casting EASIER.
But I don't believe you came here to do anything other than crap on the game to a bunch of its fans and that isn't very "4 decades-old wise" to me. If you have constructive criticisms or suggestions, feel free to post those elsewhere but being purposefully antagonistic just doesn't do anything.
