When I started playing Arcane Legends, I took me ages and ages to choose a character. Truthfully, you shouldn't waste too much time choosing like I did.
Just have fun. If you're a girl, you'll probably have the most fun being a rogue and the same for a guy as warrior. Sorcerers are small and kinda creepy, I wouldn't choose it, but you can do whatever you want. Don't over think everything, that doesn't mean you shouldn't play well, but being more relaxed about things, makes Arcane Legends a lot more fun and enjoyable.
