Hello , there.

Many of the guys above me said very true things like : F2P will never be able to catch up with with top spenders in like 30-50 years depending on rng in powering up items. You need to play with that mindset and have fun. Statements like go all-in power and ignore events ninjas are false , because you have ninjas like Deidara [ Edo Tensei ] , Konan [ Angel of God ] , Hiruzen [ Edo Tensei ] who can win you a lot of fights even if you have a lower battle power. To do that however you need to stack your position 1 ninjas which is your main damage dealer and build good support ninjas around him. This will take you some time of course but it's worth as when I was 73k battle power managed to win against a guy with 95k battle power , but he wasn't stacking his position 1. Why do you need to do that ? Well the answer is simple when you have more initiative on respective positions with your enemy you go first which will result in doing your damage and as well cc maybe , depending on your line up. When you have more critical your chance to crit increases and when you have more injury , your ninja will deal more damage when he crits and respectively will receive less damage when the opponent crits. Deidara [ Edo Tensei ] benefits the most from this.

As far as level freezing goes , if you are f2p you will want higher refines which means you are pretty much obligated to freeze. There may always be a top spender in your sage but the chances for you to obtain 2nd or even 1st place is way higher compared to if you don't freeze

As far as rushing things. My opinion is that rushing ninjas isn't mostly good , because f2p and even low spenders can't keep up with the meta when top spenders obtain them instantly most of the times. Gameplay updates such as : powering up systems , version updates and new shops are very important to f2p people , because it brings you more variety and easier power up.

As a last note be very careful with your resources and enjoy the game as much as possible.

Peace \\//
