Agreed, not a fan of the higher forge costs.
But honestly it's not just that Max forge went from 72-90k. But lower levels have now been priced out of viable weapon crafting for rare weapons. Common appears to be unchanged, but reports are that Forge level 8 costs 78k to craft, which is higher than the old MAX costs, which was already a ton of gold to spend on one weapon.
This is one things that definitely needs to be reviewed. As a veteran I will just keep farming and build as I go, it will take me longer but it's do-able. But for new players, they stand no chance of crafting rare guns due to the massive skyrocket in lower forge prices.
For those reading, no points were lost, but max forge is now level 20, which happens at player level 199.
