I'd rather not do a contested roll out of 100. Otherwise, the bonuses from strength will always outweigh weaponskill, and always result in a negative value to parry from strength/weaponskill. Or if it's the other way around, you'll be nearing 100% parry. Neither are good.
Item stats, though - Parry% from items is added to the contested defense added from weaponskill, much like the tooltip for the items imply. Meaning that if you have 18.2% from weaponskill, and 9% from the items you have equipped, you now have 27.2% contested parry chance and have to roll a number between 0 and (100 + the offensive strikethrough %)
So, are you saying that a +10% Parry tactic, or +10% from dual wield, or renown, etc. should not improve your parry by 10%, but instead should improve your parry chance by 10% / (1 + removed defense + strikethrough bonuses), which is always going to be less than the +10% value on the tactic, gear item, etc.
For example, a level 40 attacker that has 1050 strength and no strikethrough bonus will change a +10% parry tactic into a +7.15% improvement in the defender's chance to parry, instead of the +10% value that is on the tactic.
Similarly, +20% bonus would turn into +14.3%, +30% would really be +21.4%, etc.
Yes and no - strength adds to the strikethrough bonus. 1050 strength will be (((1050) * 100) / (((40 * 7.5) + 50) * 7.5)) = 40 strikethrough from stats. This is the only source of strikethrough at this point in the game.
That means that you roll a number between 0 and 140. The contested chance on the defender is the number that we compare to the random number.
For example, let's say we have 1050 weaponskill which adds 40% base parry and have no parry from other sources. Let's say the attacker has equal strength.
Pick a random number between 0 and 140.
If it's less than 40, you will parry.
The problem is that the attacker's offensive stat is not just applying strikethrough to the defender's weapon skill contribution to parry in the method you are using. It's also being applied to the + % parry bonuses from tactics, abilities, gear, and renown abilities. I'll provide a detailed example to illustrate this.
Example 1
For 2 level 40 toons.
Attacker's strength is 1050. They have no other strikethrough bonus.
Defender's weapon skill is 400. Assume they have no parry bonuses.
The method you have implemented will give the parry % from weapon skill as:
WS base parry% = weapon skill x 100 / (350 x 7.5) = 400 x 100 / (350 x 7.5) = 15.2%
and the attacker's strikethrough due to strength will be:
STR strike% = strength x 100 / (350 x 7.5) = 40.
So the attacker rolls a number between 0 and 140, and if the number is smaller than 15.2, the defender has successfully parried the attack. If the roll is larger than 15.2, the attacker successfully hits the defender.
The proceeding method is mathematically equivalent of giving the defender a chance to parry equal to:
final parry % = <WS parry%> / (100 + <STR strikethrough %>) = 15.2 / (100 + 40) =
10.9%.
and then making a roll out of 100. Keep the 10.9% chance to parry in mind when we compare this example with the following example.
Example 2
Now let's assume that the defender from the previous example has a +20% parry bonus from a tactic, etc. The other stats remain the same.
The defender's base chance to parry based on weapon skill and % bonus will be:
base parry% = WS contribution + 20% = 15.2% + 20% = 35.2%
The attacker's strikethrough value will still be equal to 40.
So the defender's chance to parry will be
final parry % = 35.2 / (100 + 40) =
25.1%.
Now compare this value with the 10.9% from Example 1. We can see that the defender's +20% parry bonus has actually contributed only (25.1% - 10.9%) = 14.2% extra parry, instead of the +20% on the tactic, ability, etc tooltip.
This is the point that I am trying to clarify. Should the % defense bonuses count for less than their tooltip values?
