I think you should stop at one element. Don't give him all elements Maybe one more, but not all of them, that's for sure. And if you do want him to have at least 2 elements, then I think that the next elements he need to obtain is electro or ice elements if you want him to be pure DD Or give him Geo element if you want him to be balanced warrior(ATK is on par with DEF) Electro and Ice elements to infuse his Water shark and Geo element for something akin to a turtle (sharks-ocean-turtle) (I just was writing 10 minutes of text about "Why should you leave only one element" but then accidentally hit the f5 and all the text vanishes... Kill me please:_) )
