@OP,

Water Team:
Ashera has priority because her burst up has no replacement. Snow Raph can be replaced by Cthulhu and Aphrodite can be replaced by SSR Nike. worst comes to worse.... you can use SR Nike and SR Belphagor while you wait for more SSR himes.

finally.... Vohu Manah is just too good to pass over. her 3rd skill give 30% debuff x2, which is the strongest in the game.

Wind Team:
Since you have Gaia, SSR Cybele / Arianrod / Ideal are the ones you should be looking for. but you should finish building ur water team before focusing on Wind
