I get beat by new servers and my server is 3 years old

Agree, it is the worst matching system.

Hello!

10 to 20 newest servers would mean 10 to 20 weeks more or less than your server and during that time span, players from those servers would be likely to have a better ninja already so the thing about being much better and balanced is nothing. However, if your server is still within 50~60 days, it should still be a local-server matching only, which means that you should only get matched with someone within your server. Although, in some cases, players from those servers will get matched by a system-generated team that makes players think that it is already at cross-server matching but it is not (if the system detects no one is playing in your server, this will trigger it).

The arena is such a pain and struggles for newer servers at the beginning phase of your gaming but it will be better once you progress in-game by having enough good units to use for battling. Together with your upgraded initiative and a good strategy, you'll be guaranteed to get a possible chance to win a battle. Thank you.
