Agree to that.

And also, your Level - Power ratio is pretty bad. What I mean is it's normal to lose on PvP. You're Lv 80 with around 24k BP (battle power), when I was at level 80 I had 80k BP (I'm F2p it was through freezing.)

So yeah, collect ninja through Seal Scrolls and Events, and try to increase your power without getting too much exp, that is my advice. If I were you, I would even consider starting fresh server, but it's up to you. Good luck!
