So the common thought is that if caster heroes are equipped with (for instance) a spear and shield, they are less likely to get hit with caster hate from mobs.
I've been away from the game for so long that I can't recall the details. Is this confirmed to be 100% true, or is it anecdotal via players? And assuming it is true, what is the extent? Like, will they 100% not be the target of anti-caster spells? Also, is it based on mainhand only, or both? Meaning, would spear/focus yield the same result?
