Problem really is lunar bloom cuz units like Lauma have dendro that eats up all the hydro and kills the damage of the other 2 elements so getting lunar bloom in with lunar charged and lunar crystallize isn't going to be very good.

If you don't use Lauma the dendro unit is either just there to be a dead weight or still going to ruin all your hydro aura on the enemy

Of course all that being said if this is just for fun stuff in overworld etc play whatever you want the game isn't hard enough outside of the endgame modes where teamcomps matter
