I'm surprised that a weapon that requires 80 slayer and 85 attack to use is inferior to the rapier to be honest. 80 dg takes a week with dgs or (lord help you) 2 weeks with w117, it's not exactly a long skill to train. Slayer on the other hand, usually is at least a few days between levels if you're not nolifing it. Also, 85 attack is well, higher than 80 attack. I was just under the impression that more rigorous stats to wield inherently meant a better weapon. I guess I'll look forward to the lv90 tier of gear being worse than chaotics then.
