Improved Disarm and Colossal Weapons

[Arienette]

If you are wielding a Colossal Weapon and use Improved Disarm, what kind of AB bonuses do you get against various weapon sizes?

I feel like you used to get a -2 vs Colossal, 0 vs Large, +2 bonus against people with Medium weapons and it just went up from there as the enemy weapon size decreased. But from what I can tell, while I have been absent there has been some effort to decrease ABs across the board. And I am too dense to parse out the bottom line from the info on the wikipedia:

Disarm / Improved Disarm:

Regular Disarm AB Malus lowered from -6 to -4
Improved Disarm AB Malus lowered from -4 to -2
Disarm Size Modifier lowered from 4 to 2
Weapon is no longer lost instead it prevents access to the weapon for 6 seconds and during this time:
Lowers the AB of the disarmed target by 10 in each hand
Causes the disarmed target to do no damage unless they have Improved Unarmed Strike, in which case they do half damage.
The disarmed target cannot unequip or equip weapons while under the effect of disarm.

All vs. medium w/ imp. disarm

colossal +2
large 0
medium -2
small -4
tiny -6

To put it another way, since you are asking specifically about colossal weapons vs other sizes with improved disarm:

Colossal vs Colossal = -2
Colossal vs Large = 0
Colossal vs Medium = +2
Colossal vs Small = +4
Colossal vs Tiny = +6

A bit of a tangent, but I am not sure why Colossal Weapons (and 2h in general) were just made worse, when they are already the worse choice.

Thanks! When you say “just made worse”, what are you referring to? Was there a recent update effecting them that I missed?

This is what the Wiki says:

Regular Disarm AB Malus lowered from -6 to -4
Improved Disarm AB Malus lowered from -4 to -2
Disarm Size Modifier lowered from 4 to 2

While the malus is lowered, the AB malus/Size modifier of the weapon is decreased. This means that Tiny vs colossal doesn't get +12 bonus to AB, instead it gives +6. Hence the nerf.
