Sacred Haven of Debauchery

/Only Titans are worse./

Titans are actually decent units, they are strong. Their problem is that they are unreasonably expensive. I would probably call Magogs the worst ranged unit. Without an upgrade, they are just mediocre ranged attackers. With an upgrade, they are practically useless ranged attackers, and their AoE attack either has no application or hits their own units as well.
