Clerics are mainly healers.. yes. But that doesn't mean they can't do
other stuff. My friend (lvl 48 cleric) says he is very offense
oriented. It all depends on what his group is fighting. If it's a
tough solo mob, he burns about half his mana on casting (he does 565 dam
a pop) and the other half on healing. Medding whenever possible.
Clerics don't have to save all their mana for healing. Most fights I
come out with 80% mana. Soo.. I now dedicate more of my mana to
offense too. Find a happy place.
