Full accuracy/spell speed
because it is the only accuracy weapon in the game for us, and because spell speed will eventually (if it hasn't already) overtake det in DPS.

You can always use the bought or t13 drop 130/135 weapon for healer stats.

You can also beat t13 with an i110 weapon easily (from the whm perspective), and with 0 piety on any gear, so what you pick really doesn't matter currently. I choose to plan for all possible futures instead.

Also crit is terrible for whm please just stop suggesting it.
