wrong again pure spr does an can work....pure spr clerics are simply clerics who do one thing:
support...buff heal etc etc..coupled with Protect Invincible,Stoneskin an Endure an the full spr cleric is fine in whatever zone him an whoever he is supportin are in *coming from my knowledge of KR Fiesta*
Full End cleric of course is a party tank for clearing dungeons...a party tank doesnt need dmg..you have mages and other doing it for you...as for the dmg problem its nothing a few scrolls wont handle when soloing.
