hmm as for me, water with STR is a bit unreasonable... a water is a supporter type character. So needs INT to make their seals better, and on top of that a water mage can be WIT with tons of INT so you can also kill with it, and also have faboulus sealing rate. I think STR on a water character is the worst choise, but if you already did, I would suggest you to add tons on AGI and be a knight, so your job skill would be a bit of use for your team.
