Well... I just feel like... Elements boosting themselves is... a little boring or something. o ^o; I mean, I wanted the strengthening system to involve different Elements so that there were more relationships between them all besides just 'strong against/weak against'. And besides, there are the Elemental Boost Traits which, although maybe not accomplishing the exact same thing, could be considered as an Element being strengthened by itself (if you put it on a pet with that Element).
Water and Ice – I guess I could do that. o ^o I kinda wanted to avoid it if possible, but it does make sense. I wonder if I should have a vote on this, too? XD
...And the vote for the current question is tied. o ^o Vooooote, other people~
