I agree that the Fatboy is by-far the worst land XP. It suffers from high cost, fragility, low speed, low DPS, and huge hitbox. Although it can win against other land XPs when microed and with radar, this comes at the cost of vulnerability to T2 arty, tml, bombers, battleships, nukes etc etc. Given how easy it is to counter, the fatboy should be as cheap as the Monkeylord.
