my 2cp
like all others have stated, race dosn't realy matter in the day to day role of being a cleric.
myself, i chose halfling. i did it for several reasons, the exp bonus, the ability to see at night, the ability to sneak, the ability to hide, and the best ever starting zone for a noobie.
the only one i would concider after halfling would be DE, and thats because of the snare. but that wasn't enough of a reason for me.
i can't count the number of times i have used sneak and hide.
find a merchant that won't buy/sell from you? go behind them, hit sneak, and poof, they love you.
this worked great when i used to hunt in runyeye, is great zone for a young cleric, used to be decent pp, what made it great for a halfling was at the bottom of the zone there is a bank, and merchants to sell your VT to. but without the ability to sneak, they won't buy from you after you killed so many goblins.
this also worked great when going for the ring (epic 1.0) you need from the goblin in...hmmmmm.. sol A? when doing that camp, you could kill all the goblins, then go sell all the VT to the merchant there as well.
and omg, i remember my LOiO days, using sneak to sneak into the sarnak fort to get to a ledge group lol.
so to me...
halfling>DE>then any others beside human...but i put human at the bottom cause i hate it that ya can't see! well eurudite right there with em ;-P
