I agree, that's how I play my cleric... people say "making a hammer +9 is useless" and i think they're totally wrong!
I'm good at soloing, and I can be in a party to heal.. or Duo with a fighter and I can do just as much dmg!
Clerics can multi-task.. you just need to be fast and coordinate well (which I am still learning...

)
Cleric is not an easy class to play if you know how to make use of ALL your abilities!
EDIT: we cant match a mage or archer, then we go into healing mode (it also depends on wat u're training on)... but we can most likely match a fighter, and I can do fight + heal while he stuns...
My cleric is Crit built as well, so I actually do a lot of dmg through crit
