Arena has always been a problem. It has been discussed in length in many posts and nothing ahs changed. The devs either don't care ot simply can't change things.

On the other hand, the problem you faced today is that everyone is trying to complete their arena missions. Including some very strong players. Wait till sunday or monday and you should find things ot have gone back to normal.

It's the same thing for matsuri, never do matsuri just after it starts of just after 9 tails. You will find the strongest players at those times. Arena ranked matches also become easier by the 20th of the month.

Unfortunately that's pretty much all you can do to solve your current predicament.

People usually do that when they dont need wins, just arena participations. I personally go with main + konohamaru corps and pervert kakashi xP.

Anyone can beat that team and i find it funny.

As for ranked arena its simple. To reach six paths sage you need 3 things: A strong meta lineup with move 1 control or DP hidan, over 12k total initiative (Yes 12000 initiative adding your 4 ninja's individual init) and after all of that you alse need luck. Exceptional cir*stances such as a big shift in the meta (han when first released) allowed me to reach sage with only 10.5k initiative, but such cir*stances dont happen often.

GL in your future arena endeavors.
