You forget that in this game, when you start over, you almost really start over. No way to transfer silver from your dead character, some items might be class restricted, you don’t get to keep hidden quests that you have completed, and a bunch of untradeable stuff like monster gems or cards and certain equipment like Ledas shield will stay rotting in that character forever.
You may think it’s not tedious to go through each map and 100% them over and over, doing all side quests along the way, but it really is.
And again, your character is just there. Staring at you, providing no use for you except just be a candidate for deletion. And you then remember all the fun you had with it like quests and meeting people and other aesthetic feats, and all because of a few mistakes you’ve made that lead your class to either be bad or useless in the late game, you’re just forced to abandon it for a class that would fit more for your style or would be decent at late game.
You also then remember one important thing you’ve spent on that character - your precious time and effort over the weeks just working on him/her. Imagine if you could’ve instead used that time you have invested in that character doing more productive things like watching a couple of movies, practicing a sport, learning a new hobby, going on social activities, spending some overtime work for more money, or even just doing in-game things like farming for materials or boss hunting. All that time and effort just goes to waste because you’ve made a silly mistake or that “you haven’t researched enough” as if this game was some science experiment or something.
We shouldn’t forget that this is a game, not a lifestyle or career. Doing mistakes in life and learning from them should only really be a part of real life events and scenarios, not in games where the goal is to have fun.
A controlled circle reset system avoids letting all the time and effort you’ve invested in the character you have raised go to waste, while making sure certain builds cannot be completely abandoned or replaced by trending builds. Simply enough, they can do things like a singular circle reset at a time, or limited single reset per character, or just extremely high costs so that even those who have been able to create a strong build would feel rewarded that they didn’t have to go through the painstaking process of circle resetting, which will depend on how IMC would want to implement it. Nothing is unfair from a reset because it’s what it is; a reset. They are not adding anything to that reset, it just fixes a mistake for your convenience.
If I were to complain of something P2W, I would look more at things that simply give a very big advantage versus players who don’t spend money, like Enchant Scrolls. I mean, giving up to three additional property attacks from a cash item seems pretty broken to me, but I guess the stats from those do fall off late game.
