Glorious claymore bugged?

I was testing both my +13 glorious and +13 bellum claymores in PvP and found that the damage they deal are too close to each other. I have 100% pierce so harddef does not matter and I have a lot of crit damage% some atk% and ~500+Atk.
With MB buff My bellum CS can reach up to 850k but my glorious can only barely reach 900k as if it had lv1 slaughter. Lv 2 slaughter should allow my damage to reach 950k.
Can anyone else test this if its a bug?
Can anyone else test if

Bellum atk = 260
Glorious atk = 220

Bellum weight = 350
Glorious weight = 0

Crush Strike:

Skill Damage % = [{Weapon_Lv × (Weapon_Upgrade + 6) × 100} + (Weapon_ATK) + (Weapon_Weight)]

Of course I accounted those parts of the weapon and skills.

Crush Strike with that Bellum Claymore deals 8210% damage, with Glorious it deals 7820%. 

More importantly, Bellum has a higher base attack, wich is also further scaled by STR at a better rate than Glorious. Base attack alone the Bellum is 18,18% higher.

Lastly, both weapons have very high demihuman dmage, and race modifiers don't apply to all the portions of your ATK.

Vellum could be a stronger weapon but generally people will still pick glorious because it works outside PVP/WOE and it doesn't break.

Unless you want to run around with FCP all the time, the glorious claymore is just more feasible for Crush strike.

 

Also, you have to account for the fact that we are now in a OCP filled server, so there's a many sources of ATK going into your equipment. This makes the effectiveness of Vellum's higher base atk and weight play a stronger part than the raw atk from slaughter. Before OCP, the slaughter ATK bonus would make it way better than vellum. That would also explain why your damage is close on both weapons.
