We don't want to spam players who are leveling. Someone going from 45 to 46 in a dungeon shouldn't result in a bunch of spam before they've had a chance to level.

For level 70 toons, we should warn on any low-rank used.

For sub-70s, we should give them a grace period of 1 level before sending them a message.

This requires testing in instance, specifically testing some one who just dinged and is now 'technically' using a lower ranked spell.
