"Don't use it" is a really dumb argument, even singleplayer games need to be balanced.
I already covered that at the beginning of the post.
As I said, it's situational. Something like a weapon type being OP would need to be balanced and simply saying "well don't use that weapon type" won't work because then someone is being sidelined from using that weapon type.
In the case of a respec, nobody is being sidelined.
There is no imbalance if it's not being used; there is only the possibility of being an imbalance if someone exploits it; and if it is .. it's not my game that's being exploited, it's theirs. Don't see why I should be denied a free feature because some random person can't play the game without exploiting it.
¯\_(ツ)_/¯
If you play a tycoon or city builder game and there was a building unlocked halfway into the game that was free and generates you tons of money, would you also say "You don't have to use it, it gives other players options, it's a singleplayer game afterall"? Lmao, thats simply bad game design.
Yes, actually I would. :P
Would I use it? Maybe, probably .. okay, totally. FREE MONEH!
Would others? Maybe not.
So what? Still my game, still my experience, still my decision if I want to use it or not.
I don't abuse the system the way I described, but simply it being so easy to exploit devalues the whole experience.
Only if you care how other people play the game; which I personally don't. My experience is no less valued than what it was before I discovered the free respec; nor has the value changed knowing that people exploit it.
If someone wants to exploit it and, IMHO, ruin the experience for themselves - so be it; it's not my problem.
I say 'don't use it' because you really don't have to use it. You don't have to experience it. You don't have to interact with it in anyway. You ignore it, and you continue playing the game the way you want to play it and let other players play it the way they want to play it.
