I voted for drops to be the same as OSRS as this is one of the few, if only, RSPS which stays true to OSRS and would not like that to be changed.
How about adding the same drops as OSRS but increasing their values ingame, e.g. increase price of Dragon Plateskirt by 10x? This would still provide an incentive for people to kill revs because they would be more profitable than regular bosses, such as GWD where drops are worth 30-50m.
