you would never get that counter attack, if you were down to what 3 unkillable fields. First you get the furballs whining because we dont have dar, that takes away a big chuck of your possible play countattack base. Second you wouldn't know where the enemy is coming from. the Buff dweebs would go roundtheclock HQ/strat raids. Thrid again you have the nonstop vulch n00bs.
typical player reaction.
"dar down, alt monkies in p51/spit/lgay7/nik 10k above field outta ack ranger, outnumbered, im outt here CYA "
