The Myopic Sniper

They have gone way too far down the symmetry hole with their subclass picks so we end up with niche picks like Clockwork Sorcerer there purely to balance out the Wild Mage, Clestial Warlock to balance out the Fiend, etc. If each class had 8 subclasses in the PHB perhaps this would work better, but with four I would rather all the selections be a bit more iconic.
