@ThunderTF2 True, but Arc Lightning is good enough to mow down big waves later in the game, unlike supports without AoE abilities who struggle to defend the base later from just the creeps. The point of Zeus support is not because he has decent nuke power and de-ward skills, they are decent but any support have some strength and weaknesses. The thing is - Zeus will have global presence from one point onward with a lot of utility. No one can fight under Nimbus with the enemy core, despite Nimbus being casted from support Zeus or core Zeus. That damage, detection and stun are still there. And the ability to use it, while being in safe location is what makes him good support. Nearly the same stuff is what makes Silencer good support, despite his ultimate being on ridiculously long cooldown, being negated by dispel and other weaknesses the hero has on it's own. It's hard to kill him before he use his global silence - he can use it from his fountain. I'm not scared of over-farmed Crystal Maiden, her spells are good and all, but a core can just two shot her if she wish to use them - fuck her. Global presence is something which supports love, they are safe, far away and still manage to impact it in some way.
