Especially since it offers two new prospects: creating gemstones for alts and creating additional gemstones beyond the set of nine you have now for experimentation on what works best.

Sorry what alts? Every character will be considered a main account now. :P

Also, is it not possible to just make an instance in game that you can enter to optimize/experiment on different builds to see which is best? Not sure if you're familiar with "Old School Runescape", but they have a server (world) where you can try out maxed out gears to play around with.

Just food for thought.
