I don’t talk about this as much as I used to in other games because ToS is such a low skill game that it barely applies but a good/balanced game should match it’s skills/classes input to their output.
Cost + Effort = Reward.
Obviously everything in ToS is low effort so not much to be gained there but there is costs.
Blind Faith costs half of your SP, compared to lets say Death Sentence which probably costs about 200ish. Let’s assume the average person without trying has 10k SP, if that’s the case, by cost alone Blind Faith should be 25 times stronger than Death Sentence. Now obviously that creates a massive issue with it being way too strong. So if you can’t make it that strong, perhaps it shouldn’t cost this much…
Luckily these classes have other strengths to kind of hide this, but Blind Faith is bad compared to other skills that serve the same purpose. If the other Zealot and Oracle skills were present in both classes and you had to choose one or the other, nobody would ever choose Zealot.
The original poster may(MIGHT) want SP pools to be buff to make this skill stronger, and whether or not you agree with that is your own opinion. However this skill does need a buff of some sort, because in it’s Rebuild state it’s very very bad. What makes it especially bad is that it’s still good enough to take, it just doesn’t have the same Reward it used to.
If you don’t use it you lose out on a lot of extra damage, but if you do you gain an increase about as strong or maybe even weaker than other classes that have simular skills but you get a much harsher penalty.
Cost + Effort = Reward
You can’t get something for nothing but you shouldn’t lose something and gain nothing.
