YMMV / AirMech

• Game-Breaker: fortifying any given zone with enough Seekers can basically deny that zone to the enemy team: until later levels, they simply won't have the Hit Points to withstand that kind of Anti-Air Macross Missile Massacre. One option is to airdrop ground units, which Seekers can't shoot... but what if they're on an island? (On a more positive note, Seeker saturation can also help shut down the "leaving a tank on your porch" tactic the Co-Op Multiplayer AI seems to so enjoy.)
• Goddamned Bats: A small example : When you're transforming to ground mode so you can pummel AI when it's supporting their units during said "leaving a tank on your porch" tactic, it goes back up and fly away just as you're about to fire.
  • As for units, there is the primary unit everyone loves: Buckies. Get a group of them together, nothing is safe. Get a thousand together, say your prayers for everything. Unless you have some defensive units or Aegises a plenty, defeat is sure to be inevitable.
• They Changed It, Now It Sucks!: occasionally pops up after a patch, but never moreso than upon the introduction of Auto-Deploy V2, with many top players leaving the game.
