Tried and tested this with friend, and this is a lie.
If both builds unload the spy build will make more cos they have consistent plunder and attack drop spectacularly
But if they both skim the attack build will make more, much more, because attack build produce the highest plunder, scratch that the defence attack builds make the most plunder in game.
And that is why defence attack builds are awesome, so do not mess with us eb fairies, because you do not want to anger the noob inside us eb fairy defence attack builds. We will utterly destroy your ass. And that is a approved Wolfie comment because we will do it.
