Manastone use, Druid or Cleric

[zelld52]

Making my swan song toon. Trading a bunch of gear for a manastone. Gonna either play druid or cleric with the manastone.

Have a fungi, have Seahorse Belt, have tons of HP gear. Would a cleric or druid be a better bet for levelling my last toon casually (1-2 hours per morning)

I've got a 55 cleric / 51 druid I can toss the stone on. Would a cleric be able to solo 55-60 with manastone? Straight up nuking mobs?

Or would druid be more successful with manastone?

EDIT: If I picked up my cleric, I wouldn't need Fungi - but I was considering rolling a new cleric for luls (and lulls)
