It's the same people who think the BT will help them being better. Also, they think the negatives effects of what it can impact overall but just want the positive effects for themselves.

Unless you're playing on the HK server, any proof they removed naruto (and I guess Sasuke) from fateful? I had to check on Discord and apparently, its Minato (I think Edo) and Madara GNW.

You're right that it's better than stacking with pay-only characters since it *s that ninjas like naruto ronin is still locked behind a paywall or listed at a 40K+ coupon price. However, you can tell when people ask for certain BTs and ninjas at large rate, the options they choose tends to be available to f2ps. Whether some think getting their BTs will help them be better is up to the person. However, in fast pvp matches like sage, I know one of them will use it there which will make matches slower. Whales won't use naruto besides space-time or maybe even GNW since they have better and faster lineups. So slower matches will only occur for f2ps.

When I meant by slower is that f2ps that went from naruto to Kakazu/edo minato to kisame/edo minato might end up deciding to go back to naruto thinking he is OP. They ignore that they might get longer matches if they are currently using kakuzu/kisame. For the case of edo minato, it might be faster since his dodge drags on the match.
