Quantum's Take

Constantine is one of the best AoE chmapions in the game, and he's on a team that is relatively obtainable by non-spenders and lite spenders. He has an AoE on both his ultimate and one of his basic skills, and you can get a third AoE if you have his unique legacy piece (which is required if you're building Justice League Dark). He does heavily rely on his teammates (at least a three-tag bonus) to provide additional Spiritual AMP, but he sees plenty of action as a plug-and-play unit when there's a support champion who can boost ATK..
