Base recharge times for staves have been increased to such an extent that even with a large amount of investment (keeping one equipped all the time and exclusively using it for melee) they often recharge slower than they would if zapped from the backpack in 3.0.2. For example, blessed staff of strength used to recharge in 400 turns if zapped from the backpack and 200 turns if zapped while wielded; now its base recharge time is around 1188 turns. In an ideal scenario where you are attacking and hitting every single turn it now recharges in around 300 turns; in a more realistic scenario where you are attacking perhaps once every 10 turns, it now recharges in around 540 turns. With a lot of effort invested in a single staff, you are getting worse results than minimal-to-no effort got you previously.
