Thank you for putting all your hard work into the new updates, I really love it. I would like to offer some insight though.
2.0 Arena
The idea of the new arena is awesome. The idea of it, to the new look of it, everything is great. Except for one tiny flaw that seems to be aggravating everyone. 「you will be matched with someone of similar rank and battle power」. Naturally, everyone thinks they're going to be matched with anyone that is their same rank (Six Paths Sennin), but this isn't the case. Their number rank (72/71, etc.) has to be the same, which leaves only a small pool of people to match up with, so essentially you have no one to fight - which is the case for most people that try to fight in ranked arena battle. I would change it so anyone with Six Path's Sennin, Super Kage, etc can fight anyone with the same title ranking instead of the number ranking.
2.0 Team Instance and Chase Missions
This is by far my favorite parts of the 2.0 update, so thank you. All of the rewards have been substantially increased and the whole system is more functional, so I really appreciate this update. The new chase missions are absolutely welcome and loved. Getting the chance to collect rarer ninjas is awesome.
Nine Tails
The Nine Tails change is the one that a lot of people are upset about. The decreased rewards for similar damage output (Or decreased like my poor fire, lol). I'm guessing it's like that because there are more ways to get coins, like if you choose to do convoy instead of plunder. The decrease does seem a bit steep though.
That's all I have for now. Oh thank you for Sasori too. ^^
