We are not the only ones who have CAs that use arrows. But we do have way more than anyone else. A guildie woodworker is willing to make arrows for me at cost, but I don't have the heart to ask him to spend all his time in a TS instance to supply my habit (approx. 15-20K arrows a week). Besides, fuel cost is only 1 silver less than buying from the vendor.
At level 55, I was happy because I used only 2k arrows a week. But face it, the game at lvl 70 is way different than it is at 55. It's much faster paced. Whether you raid or not, the game is still much faster. No one want s to spend 2 or 3 hours in an instance. Get in, clear it, and move on to another. I remember when Lab took four hours or more. Now it's cleared in less than 2 hours and you're just warming up for something bigger.
I use my reclaimed arrows everytime it's up and I still spend more than a plat a week on arrows. And frankly, it irritates me to no end to hear a 50 somthing Ranger state that they don't have any problems with arrows, that they always parse on top, yada, yada, yada. Just to have them comeback two months later and say that they now see just how costly it is at higher levels.
