Im sure any spam is not Relic's intention how to play the game. So balance developer spamming kubels, jeeps, E8s and abusing game mechanics to troll and making it less fun for people is definetely not how Relic wants the game to be played. And its not making a good image about Relic/balance department.
Ofcourse you can play the game how you want but the biggest problem is Relic employee is involved in here.
