I think that an Omni-Protection Prayer is too overpowered, definitely for monster hunting: however, I like the idea of being able at, say, level 90 Prayer, to activate two protection prayers at the same time. Sort of like Summoning + any other protection prayer, but now like the KQ has, for example Protect Melee + Protect Ranged. This would also help sort out the PJ problem in PVP; Prot Melee + Prot Ranged protects from both D Claws/AGS and Dark Bows.
