Only thing I'm against was restricting the training inferno feature to Uber+ as the benefits for both donator ranks are sufficient as is. I'd rather this feature be open to regular users also, so they can use it as intended, for training.
Other than that this was a brilliant update, .
People have called the perks for ranks like Master and Immortal "underwhelming", so Dan and I try to think of perks that aren't overpowered, but unique and beneficial, which is how inferno training came to be. I understand everyone could probably benefit from it, however it felt like something useful and not pay-to-win or overpowered to give the higher ranks as a perk. The perk itself was conceived as a way to provide better perks to these ranks, since all it really saves is time, and even upon completion nothing is awarded.
