Elemental Staves & Wands Known Issue

What do Bishops have? HS, invincible, elemental resistance, and holy attacks (granted, there's much more than that but in terms of leveling, this is all that's important).

What do A/Ms have? meditation, ele amp, partial resistance, spell booster, and elemental decrease.

You forgot to mention the new toys Bishops got with Big Bang that bring their damage up fairly nicely. Not that I don't see what you're saying, or don't agree with you, I just felt like pointing that out. I haven't done the number crunching myself to see how that extra crit stuff fairs against the boosts Arch Mages get exclusively.
