Honestly I happen to be a water main (free player) myself so i'll see if I can help u.
In terms of ninjas, I love gnw kankuro, kakashi, hinata, and main with the small katsuyu only problem is kakashi is fairly weak defensively so if he's targeted he can easily die, give him defense and resistance so he can survive longer, I also prefer to be the healer on my team. Not sure but I hope this helps a bit.:loveliness:
