Fire is not on good spot, maybe early game fire, and pvp fire, but late game pure fire is complete trash, is the worst pure color, loosing to even frost, all because the lack of sustainability, what fire needs its a spell that help units stay in the fight, doesnt matter if they have high dmg, if they are already dead.
you missed the point of moloch, its not supposed to compete with batarial, its suppose to be a tank, sure some colors are better at some stuff than others, but that doesnt mean they can only do that, Moloch should stay at fire, maybe reduce his power as a buff, but the 90% dmg reduction its exacly what fire needs, maybe ad a swapable option to moloch, that its either negating 90% of range or 90% of melee, cuz it gets destroyed when in melee rn, because fire has no sustainability, or maybe buff bloodthirst
