Agree 100% just because there's information out there on how to effectively and efficiently play your class doesn't mean you should. You're robbing yourself the experience of self discovery and hundreds of hours of trial and error.

Sure you'll feel behind compared to your peers, likely play a garbage build, get frustrated and likely quit but you'll be doing that with your head held high full of pride and ignorance.

I'd also recommend not even using a mouse as that makes movement a bit too complicated since you'll have two pieces of hardware to worry about (who wants that), stick with the arrow keys on your keyboard for more worry free way of playing.

Oh and if you plan on snacking during your journey, I also strongly recommend going out and hunting your own game, maybe make a jerky or something. Just remember not to follow some min max recipe when you prepare it though.
