I remember this from a different shard. Just like ores there were different levels of logs. This would increase the number of archers out there as we can craft better bows also people would be more interested in getting the runic kit for fletching. At the same time we would be able to see some bows other than the horselord around. Seriously every archer has the horselord.
To craft a better bow just need a Runic Fletching Kit. Save up the virtue skulls.
