It was mentioned in the patch notes. But they did not indicate how it was changed. So I did some quick testing as I was curious about this too.
Stone Axe (T1)
Q1 - 1 mod slot |
Iron FireAxe (T2
Q1 - 2 mod slot
|
Steel Axe (T3)
Q1 - 3 mod slot
|
Pipe Pistol (T1)
Q1 - 1 mod slot
|
Pistol (T2)
Q1 - 2 mod slot
|
SMG (T3)
Q1 - 3 mod slot |
Overall, I think its actually a decent change. They've also adjusted the damage and block damage values such that a Q1 Pistol is better than a Q6 Pipe Pistol supposedly according to the patch notes. Based on what I've seen from spawning in those weapons, it seems to be the case as well. Considering the current system where we need books to progress tiers, it makes alot more sense too.
