Feedback about Destiny warriors

I have been playing this game and i am encountering a major problem. To make short, in this jrpg that is a parody of Naruto, enemies level scale on your team level.

This would be ok if your power actually matched themm, but it does not. I am currently using legendary weapons purchased in magma rock, and best armors currently available. My attacks do ridiculously low damages on enemies of the same level, no matter the strategy i use.

I do not understand at all why some attacks do almost no damage when other attacks which cost the same amount of magic energy do ten times more damage.

I made a short video about my problem to find out where the issues comes from, i would like to kniw if problem is the way i play or related to the game balance.

In this video, even using most effective skills currently available to me, fights last forever and i am forced to use healing medics again and again.

The problem is devs do not seem active on the steam forum and i havent find a good way to contact them since epicgames forum seems barely active

On the other hand, some players game is too easy because you can actually buy several times the whole stock of weapons of a village after completing a mission, you earn lots of ryos. I feel a lot of players gave up early so its not easy to have a feedback , i played in hard mode but currently the game seems unbalanced, no matter the combos or equipment i pick.
