I would like to please suggest that we remove the fact that people get blinded after getting hit by (and passing the save of) a Word of Faith spell, because it feels inherently unfair that someone, with a summon out, can have an almost permanent blind against someone, that is spammable.
Either that, or maybe giving WoF a Cooldown between casts, even if it's like a minute, or even 30 seconds. WOF spam sucks to fight against in PvP combat, and with a such a short blind on passing the save, remove blindness/deafness potions don't have much use against it either, the most you can do is run around blinded for a few seconds, until it wears off, only to get hit by another one a few moments later.
