I have a question to those who drag:You're probably applying way too much pressure. I only have to change my pen nibs every few months, and even then they aren't that worn out, I could probably reuse all of them with no issue. Try to relax your hand a bit more and apply less pressure. I used to change my nib more often back when I got my tablet and used a smaller area, because I had to tense my hand more which made me press harder onto the tablet as well.
How do you keep your pen nibs from being eaten away within the span of a few days?
I have much better cursor control and snapping while dragging, but my pen is visibly being eaten away after only 2-3 maps...so I force myself to hover. Is there some trick to longer pen life? Or am I destined to learn to hover...
You could also buy lots of spare nibs, that would probably solve your problem as well, but I've never had to (still using the spare nibs that came with my tablet, one year after).
