Currently, Ground & Air Players using Unstoppable Wagers are able to achieve their Wagers.
Ground Players can get Heavy Metal Hero/Fury, and Air Players can get Hero/Terror of the Sky, Thunderer, Antimech, Tsunami, Rogue Wave for AI.
Naval players can only get Tsunami and Rogue Wave - However, most Naval maps have ZERO AI units - Meaning if you use this Wager in Naval, some games have a 0% chance of success. Which is unfair.
I suggest to include the 2 Player Kill Objectives into the Unstoppable Wager.
