That’s only for the blaster-caster subclasses though. The subclasses that are more likely going to go into melee (mostly the ones who get heavy armor proficiency: Forge, Life, Tempest, Twilight, War, and many other subclasses) get Divine Strike instead. So a cleric build that takes 8 levels of the subclasses that get Potent Spellcasting would be unlikely to use True Strike by then, they’d likely hang back and spam Toll the Dead or Sacred Flame (or a ranged spell).
