Caps for fletching and weaponcrafting rise in 1.64 with the introduction of the fortified and exceptional weapons which are the more varied speed 16.5 dps weapons. Further rises are in TOA with legendary weapons which need 1080 skill (I think from what I have read) plus the help of an alchemist.
Wonder if the cap increase may be high enough to allow secondary skills to be raised high enough to be useful. By this, i am referring primarily to the ACer's tailor skill which is currently set at 75% of base AC skill which means (for non-acers out there) that an armourcrafter cant make all the necessary base leather for AF102 scale.
You need a SCer, Alchemist and either a Fletcher or a WCer (depending on the weapon) to make a Legendary Weapon. Legendary Weapons do Elemental Damage so not sure what that means (as if in does it do less damage if a mob has a certain kind of resist...)
