I mean I could agree on the Ava's being overly expensive, but I disagree on the price of the infernal. Infernal is expensive as fuck to obtain on 07 itself, why make it any easier on this game you know. The only reason the Ava is in the equal price range is because it's the only way to really ''freely'' obtain it, but it's a very rare drop.
And for Ironmen, we're already working on things to place for ironmen. We're trying to make everything obtainable for them and definitely do consider stuff like this to be very hard for them to get. Just wait mate, changes will come.
