While we're fixing leaps, here's a reword of Mighty Leap. I think this one was named for distance and not height, but they're the same, so, lucky us.
The current power doesn't specify whether he takes LEAs or not, so I assume that he does, though he'd ignore most of them due to Tiny Stealth.
MIGHTY LEAP 5
Instead of his normal move, Ant-Man may use Mighty Leap. Mighty Leap has a move of 5. When counting spaces for Mighty Leap, ignore elevations. Ant-Man may leap over water without stopping, leap over figures without becoming engaged, and leap over obstacles such as ruins. Ant-Man may not leap more than 5 levels up or down in a single leap. When using Mighty Leap, Ant-Man will take any leaving engagement attacks. Ant-Man cannot attack on any turn that he chooses to Mighty Leap.
