I think that this statement is very true, but on top of that, balancing weapons automatically may cause some serious problems. Populariity is not a good measure of quality and balance unless something is severely under/overpowered(Which is the case in CIU now). Such system would almost certainly break once the weapons get relatively balanced.
For example: weapon A is slightly stronger than weapon B but is much more difficult to use than B. A is less popular because of the difficulty. Then automatic damage boost makes weapon A even stronger thus making it objectively better than weapon B. So then A becomes more popular… (And so on, basically total mess)Nope, it’s not gonna work in any shape or form.
Once everything gets to the relative balance, dealing with weapons that are too strong, or too weak can be done by slightly buffing/nerfing said weapon. This is the balance tactic that is used in many games and it works really well.
And it should never be based on the popularity. Low popularity doesn’t always mean that something is underperforming. If you look at some other games like League of Legends for example, best meta characters are almost never the most popular, unless they are completely overpovered.
So yea, IMO this solution may potentially cause more harm than good. And definitelly will not solve all the problems that need to be solved.
I am happy that community likes my work, but please remember that it’s still only a suggestion, and it’s up to IA whether or not WBP becomes a thing.
