So it's wielded in some cases, and is not wielded in other? How in all 666 infinite layer of the abyss is someone supposed to arbitrate with such contrieved and literally opposite rules? Coin flip?I heard emotions are hard to read on paper so let me explicitly state that i'm quite pissed.
It's because they're drawing a line between what they consider "letting it be useful" and "letting it be abused."
Mind you, I'm not saying any given example would or wouldn't be abusive, in my own opinion (reserving judgment there). But from a game design standpoint, you tend to want to let some stuff go through (e.g. Kineticists aren't likely to use STR at all, so not allowing Weapon Finesse means Kinetic Blade gets dumpstered). While also remembering that you usually can't let *everything* through (e.g. It's probably not a great idea in the long run to let Kinetic Blade qualify for things like Weapon Training, Weapon Versatility, etc).
Minor edit: I was referring mainly to a more vanilla blast-you-all-day Kineticist when I mentioned that they aren't likely to use STR - though, one certainly can play a STR-heavy Kineticist.
