Actually, it doesn't make more sense for the option 1 when the nerf is based on the latest chars. A character can be nerfed but still better than others, the result will be -> still OP. All characters needs to be 70-90% equally between them if you look for "balance".I will re-write something I just added on a previous post:
To bring more balance to the game you can have two options:
1. You can nerf very few characters, this is a few hours/days of work.
2. You can improve many characters, this is week/months of work.
It only makes sense to follow option 1, even if it is an unpopular decision.
Yes, you can nerf Chungha & RCaisse to a certain point, but compared to other chars, they're still OP. So what will you do afterwards? Work a few more days to balance them a bit more? If even after that they're still OP, will you just say "Well, they are latest chars, obviously needs to be a bit stronger."? Then the whole point of balancing was for naught.
Right at the beginning of the server, MSB, Canna, Chungha, Moon, Charlotte & CLio were already nerfed, but still better than 80% of the total characters out there. You will nerf them more so they're will be a balance between them or between all premium chars?
In the end, the 2 questions will be: 1. What would a balance/nerf to a certain character bring/do compared to other characters of the same Weapon-type/Usefulness/PvP-oriented/PvE-oriented ?
2. If that certain character will be nerfed to be on par with a different character, why the range (latest released char from MSB onwards) is so small?
