I don't see why whms need an auto-refresh. Higher tier cures make the mp gained from the trait almost unnoticeable. If anything, whms should get conserve mp, but that would just be redundant due to the ability to sub sch. In the long run while spamming cures you'll notice that you have a larger mp pool with conserve mp than without it; and if you are idle waiting for those few tics of mp why not rest. It's not like kneeling down will kill you. In roughly one second you can be up curing your tank without any setbacks.
