+1 (For NPCs only)
More teleport spells would be cool too. Give people a reason to get 80+ magic besides pking/staking.
More (non-wilderness) prayers would be bad ass as well while we're at it. 40 prayer is a ridiculous level cap in terms of usable prayers. There should be at least a few more prayers to make prayer a little more interesting.
But only if it doesn't destabilize the wilderness!
