1: He is in almost every single event in every single cycle so technically everyone can get him for free, the only difference is the new players are handed him on a platter whereas older servers needs to have some patience and get him frag by frag.

2: Why are you in a rush to be boring? A game that exists for the sole purpose of collecting characters but you instantly want to discard 99% of the games content and run to the finish line and use the most boring character in the entire game?, the game is at its most fun when you have just started and you c*e all the characters you like and still have a viable team, once people start getting meta thats it, your server is dead and it will never again be possible to have fun there because even if you dont care about some undo*ented ratio it simply is not fun to be trying new teams but only ever face clones using the same cookie cutter team so boring that an autoclicker could do what they call "playing" the game.

3: I hate oasis as much as the next pleb here, but your argument doesnt hold up. "new players get him free but old servers spent coupons", by that logic oasis would have to give everybody free shisui susanoo, obito ten tails and madara ten tails because there are people who spent coupons and real world money on those characters but the mods got them for free and a minute proportion of players got them from lucky wheel on a free spin. Or if you want more tame examples, naruto ronin was released as a tsuku tier reward costing more money than a second hand car yet now with a little patience anyone and everyone can get him in free events and edo minato was released in a recharge rebate only being available to people willing to spend £600 on some pixels but now he is one of the most common characters in the game, across all server ages because he was in so many events ( just like etr madara currently is) that even free players who rarely log in where able to gather his frags freely
