Im going for crit and det for my omnilex, as a scholar there isn't much sense in investing in even more piety. I have free heals from eos a low cost spamable, aetherflow and the drain skills it's very rare for me to run out of mp and when it happens im one of the last people to run out of mp. So bigger heals seems more cost efficient than anything else I wont even need the t9 book once I get novus the difference in crit is negligible which will make my novus BiS for Scholar atm.
