I have noticed that the sub-weapon is not working as intended.
Test objects:
TMQ1-3 lvl 41 Stick with Upgrade +15
Phy attack 159 + 369 -> in total 528
CC100 Stick +0
Phy attack 271 + 0
So the lvl 41 Stick has 257 phy attack more than the CC100 stick.
But when you look at the 6 attachments you can clearly see, that the lvl 41 Stick, who has 257 more phy attack than the CC100 Stick does less damage.
LVL 41 Stick does 5700-5900 on a noncritical attack
CC100 Stick does 6300-6600 on a noncritical attack.
Please let me know how that is possible.
