No its not worth it... g18 r8 will still triumph over g16 warsoul wep.... even dragon wep was better if i remember right. The extra 20 or so attack levels didn't make up for the lost refine bonus you from a g18 wep... but when we had a discussion and tested this stuff out, it was a very very long time ago.. before dt/cube neck and all that.. Anyways... no its not worth it.. at all.And as for your second query, if your asking that you might aswell have asked why we don't have r9 yet... simple answer would be this isn't pwi hence we have a lot of custom gears and what not. Aga could've used the same concept as r8 recast and called it something completely different. All that matters is that everything is balanced to some extent and the fact that no amount of fortune would grant you any uber advantage other than simply allowing you to get your shit faster.Edit. GMs can give a more precise answer as they can test this shit out whenever they want under current circumstances.
on mage ne r8 is better way better
