After reading several posts from @Mohadib and Co. I decided to go full scale and prepare my physical Mech for Insane Big Boy. I tweaked heat and cooldown to fit in additional plates, and armed with 2500 HP I started grinding Insane BB. First run, 3 repairs, no sweat. Sweet gold, sweet experience, BUT NO BOX!. I say, curse my bad luck. Better luck next time! So I go second time. This time 1 repair! No chance to win without revive. I say, ok, if I receive a good box, I can afford 10 tokens. I just died on Big Boy. Revived for 10 tokens, sweet gold, sweet exp, BUT NO BOX!!!!!!!! This time got infuriated. But calmed down and said, it is always better THIRD TIME! I set off, 2 repairs, killed BB on the last scratch of HP (physical orb hitting for +500 dmg), and this time I received sweet gold, sweet exp AND A BOX! And I say to myself, whoahhh, this is going to be hell of a box! Yes, 3 commons... 3 COMMON ITEMS. What is the risk/benefit balance? WHAT IS THE ****** POINT OF GRINDING INSANE BIG BOY? I see none. What are your experiences?
P.S. Ah, yes, I seem a bit negative again, sorry, folks!
