1. Not sure if skillups come faster with higher skill. Never seemed that way to me. Increasing wisdom made it go up faster.
2. I use class one arrows for bow kiting and normal use. The small dmg increase doesn't justify the cost. Range increase is nice if you want but not really that big of a deal unless you are competing for ftes. Sell back you expensive arrows to offset cost when skilling up fletching.
3.Quivers don't give bow haste till later patche. Not worth having one at this point in time.
4. Trueshot makes it worth it, then you can do raincaller later on. Of course you could just buy one if you dont want to. But the cost to make them is so small. You could potentially make some money off selling them to other rangers.
Hope this helped.
