The way to look at Staves is based on their elemental multi, not just the 2.15. You still won't see a lot beyond 2.15, but the elemental multis mean they can be more powerful than the elephant pike in an elemental situation. I made an update to the elemental multis to create a higher base elemental bonus too. Do a bit of woodsinging after the next copyover and let me know what you think.
