I understand that more versatility equals more advantage, but what's with "significant advantage" being constantly thrown around? That's the one problem I have with the entire argument. The buffed nymphs have, up until now, always been on the (very) weak side, so nobody can draw on any meaningful past experiences for support. The closest you can come to is drawing on the experience from purple/amber nymphs, since these buffs appear to try and get all nymphs on a similar playing level to those two. Yet, I don't recall any similar argument ever popping up for those two.
The way I see it, if the nymphs are OP, then the "significant advantage" would be fairly obvious. If they aren't, then I don't see the "significant advantage," and I ask for an explanation from those who think otherwise.
