I just got my tablet a few days ago, and thought the full area tablet surface was ridiculous and immediately started trying to figure out how to get the tiny box. I started realizing that small circles were going to be a problem and that it was already kinda hard on my wrist for the tiny movements. It felt just like mouse, which can get kind of erratic and guessy at times. I changed it to full area, and even though I'm still beyond horrible now compared to where I was at with mouse, I can start to tell a difference as to why full is better. It feels like I am going to eventually have way more control and precision once I put more hours in. I can no longer play osu! with mouse even after just two days of playing with full area tablet. The sensitivity on my mouse just feels astronomical, and I miss notes by 2-3 inches on my screen. If you really want to try and improve, I recommend going with the full area like others are preaching here. If you play at full for a few days and go back to the tiny box, you will realize how limited you feel in what you can accomplish.
I just wish this damn pen was easier to hold XD
Anyone have a good grip technique for it? It feels kinda awkward and I can't make up my mind on how to hold it.
