My build? Your opinion.

IMHO no str in the world will make a cleric kill 'fast'. if your in a party, healing others, str is *completly* useless. if your soloing, ye it helps a bit.

the most important stat for a cleric is end. a cleric needs to stay alive. 'nuff said.
after end, i would put spr. never tested it, but i think adding X spr would probably give you about the same dmg bonus -through crits - if not more then adding X str. im not sure of course, but spr definietly adds to your dmg. the SP bonus is not of importance but the m.def is. again, it helps you to stay alive, to keep others alive

I agree with your first statement, but your second statement's a bit iffy to me. Yeah I'd agree that a cleric needs to stay alive, but I've found a vitality scroll is more than adequate so far. If I ever do die, it'd be because of something completely out of my control, that endurance wouldn't have been able to prevent. Like getting hit by the Mara AoE. But this isn't to say I believe strength to be a better stat than endurance. I actually prefer endurance, because it increases your defence based on percentages (through block). If strength added damage on a percentage basis, I might be more inclined to get it. Sadly it isn't.

If strength added damage on a percentage basis, that would be a whole different matter
