Lackluster update IMO, would have been much better if they scaled down the Woodcutting levels required to cut every current tree, then added new trees from Lv.60-90.
For example, make it so you need Lv. 50 Woodcutting to cut Magic trees and Lv. 50 Fletching to fletch Magic bows, then add Elder tree as a Lv. 60 tree to make the Lv. 60 Elder bows with Lv. 60 Fletching and so on.
Have Crystal tree at Lv. 70, giving you Crystal seeds which you could fletch into bows (Both shortbow and shieldbow, make Dark bow a Lv. 80 shieldbow) with a special elven fletching knife.
Then have a Lv. 80 tree that would give you Lv. 80 logs that would be purely used for Firemaking (maybe something else too, but I don't have an idea yet) and a Lv. 90 tree that would serve the same purpose as Crystal trees do currently.
