I'm sharing this from my group experience in my server(554)

in Matsuri, all my group mate gave up, the battle is so unbelievable hard, one of my friend are level 75 with 22k power, on his 3 first battle he said he battle a person with 31k power on level 78, 29k power on level 74, and he fight a person with 25k power on level 69, me myself on the first 2 battle in Matsuri lost 7 ninja, and currently didn't have any revive potion to try again, lose the first one and then i won in the second one with a bit of luck I guess, anyway atm I was level 72 with 24k power, my first battle are with a level 78 person with 28k power (but on a superior ninja, wind main with sage naruto, gara kazekage, and AO, LOL I can't even kill the bunshin of naruto hahaha). My other group mate have similiar condition in Matsuri, where they will lose the first and/or the second battle easily, maybe the opponent searching method not based on level but also power, so there some chance for a fight, just my opinion.

in Arena, training battle was hell, I don't know why people are there using their main formation over and over again ( I met this person 4 times in a row, so I guess he didn't fight for arena mission like me). Since arena point are only obtain for doing arena mission and using first time win on newest ninja, claim victory is though with a limitation of Ninja, I try to say that in a new release server normal player in average will have 30-50 ninja, my server are 2 month old, and the rank 15 in "Ninja" have only 50 ninja, which make hard to make a combination for a new player on new server to win here. Well, like how about player with 30 ninja or so, they will absolutely skip Arena. Not to mention that in Arena the speed are limited to x1, while all the Ninja are level 100 not awaken, and I didn't see the retreat *on, make Arena take a long time only to see the "defeat" interface lol. Here I recommend maybe make only the rank battle cross server, while the training lone server, or maybe after 60 sec that player didn't get enemy in his own server, then the system will get him an enemy from other server.

It just an opinion though, and I'm sharing mine and my group mate experiences.
Thanks!

sadly there's not much you can do about it. Depends largely on your Spacetime bracket. If you are in one of the newest servers in it then means for 2-3 months you'll face very hard battles, then you begin to get nice matchings.

In my specific case, i was in server 302. Before the merge of my server i was in 295-403 server bracket and i used to get 5 victories with 40k power. After the merge i went in a new bracket (57-73 + 172-306 one) and i used to get just 3 wins by using 150 revival potions at the same 40k power. Now that i'm at 62k i get again 5 wins for free or at most with 50 revival potions every time. Is a matter of time and power. Don't give up, but don't use revival potions neither until you begin to get 3 wins for free often.

You friend needs more power... lvl 75 with only 22k is VERY low. I only spent $10 and I'm at 37-38k at lvl 78 to give you an example. The other FTP/low spenders in my group have at least 33k at 78 so he should at least be around there.

I find Matsuri ok, it's bad when you get stuck with a higher lvl that has 10k+ power on you but I have managed to get my 5 wins so far. If they could balance it a little more based on power that would be great.

Arena is working great for me. I can finally test out teams and all of that easily. The only thing that needs to be changed is the fact you need ot hit sage of six paths at least one time to get the full rewards of your rank. I don't see the reason for doing this other than scamming players out of their fragments because they did not spend $5000 maxing refines.
