You clearly dont have event ninjas thats why youre complaining. I play azure fang, and mostly fights midnight in every swb, arena and matsuri. I run with chaos passive and poisoon tai, but well here comes root. It annoys me very much, immunity and 100% buff resistance?. But still i can win cause i have edo deidara and kisame fusion. Crit scaling is real even without debuffs like ignite , poison and chaos i can literally make midnight cry with 1/2 of life taken away by deidara mystery.

Putting that all aside, you should have at least 2 event ninjas right now. Have shisui, or jonin minato or masked man. Mostly i can see in cn they using clone rather than root, cause midnight has calm mind( standard immunity).

Why not counter root? Many runs with root, mostly all the f2p goes to midnight blade and azure fangs which is no fun cause you know thwir lineup in fighting swb, arena and matsuri. Root also gives 100% buff resistance which no main can have. A little bit OP for me i think.

Right now, i have the deepest respect to those using scarlet and earth main even though f2p . Theres a few ninjas synergizes with them that you should want to get event ninjas to just maximize their full potentials.

It is a bit off topic but i rank them strongest to weakest as a moment (with of course all the event ninjas included and their uses in a team.)

1. Earth/fire main

2. Wind

3 water

4. Midnight

Well i kinda use nature enery. But it doesnt play my game style. I also try kurenai (fully skillbroke), which is good, but i find sailor sakura more effective than kurenai in spacetime which i observe kurenai always interupt by kisame. I use poison tai to complement deidara and sailor sakura standard. I dont have cc so i use chaos.

I swap to kurenai and sailor from time to time.
