eh not really TToTT boxes are now rare and expensive + premium keycards cost actual money and aren't even dropping at the moment.
Well, it's soon time for another Halloween event, which means more of those boxes. So, they might not be so rare anymore. Granted, they might be a lot different and even completely without any sort of boost bonuses, thank to premium boxes. But I'll give you Premium keys cost real money.
Con has been part of the upgrading discussion before, and was fully aware of 90%off crafting bonus when he proceeded to introduce "premium supply boxes" with their stack-able boosts.
i highly doubt this will come as a surprise to him, perhaps the magnitude of this upgrading will, but this is only possible because so very many people were willing to trust me with their precious unique items
technically, i had 110% off, and should have been refunded fuel for each upgrade :-)
Wow, that's a little hard to believe that Con could have made this on purpose. Then again, it's quite possible that they didn't expect people to still have TToTT boxes left, at least not so many that those could have become an issue for them.
But considering the current Prem boxes and their boost and the incoming Halloween event, I would say that the new Halloween boxes wont have any boosts, definitely not craft/upgrade. At least this way, this kind of upgrading won't be possible anymore.
