I'm not sure how this could be considered an exploit. They're playing the game. The developers have said that they aren't going to ban farming, how is this any different from farming? At least they're not AFK.
BTW, I take exception to the word 'sadly'. The human brain is literally physically designed solve problems and look for 'exploits.' Do you really think that putting lightning into a box and getting it to make high-speed decisions for us is 'working as intended'? If the human brain wasn't so good at finding exploits we'd still be hunting our lunch with spears instead of driving to Taco Bell.
And just to clarify, I'm not angry, I'm not upset. I am just sitting in my office on a slow day calmly typing my thoughts on a keyboard made of fire hardened oil.
