Description of the bug:

Hello,

After September update, the statistic "Weapon skill damage +%" started to work for all hits on multi hit weapon skills. Previously that statistic was only working for first hit only. It drastically changes the game balance and gear sets for a lot of weapon skills.

For test I was doing to confirm it, I was using weapon skill Guillotine, but I noticed the same for other weapon skills like Resolution, Entropy and other people noticing it for pretty much every multi hit weapon skills.

Is that a bug, or is that an intended fix/change?

Regards,
Bartek
