I'm pretty sure nymph tears can more than adequately act as a substitute. That's always been one of the problems with nymph queen; whatever buffs it receives, nymph tears basically gains the same buffs as long as you're playing water towers/pends (which you most likely are). The only buff it wouldn't see would be a lowering of the queen's casting cost.
Although, considering the buffs to several nymphs, it seems reasonable/possible that the tears will be in for a cost increase.
