Expertize ad threat

Postby yappo » Thu Apr 22, 2010 8:04 pm

I'm reading about expertise pre softcap and post softcap, and I don't get it.

Isn't expertise an aggregate roll (assuming you're not tanking the back of a mob)? I thought 26 expertize had you push parry from the roll, with dodge remaining.

Anyway, IF it's an aggregate roll, then the threat value of expertise ought to be the same all the way up to the hardcap.

Where am I wrong?

Two parts:
1) At 26 expertise, you push dodge from the roll, with parry remaining (until, I believe, 56-57 expertise, mostly unconfirmed)

2) The threat value of expertise does diminish after the softcap, but that does not mean it's a bad stat to have for more threat, especially if you're already over the hit cap (or close enough to it)

The main point is shown in the sticky of these forums, Theck's MATLAB analysis. Here it shows the obvious drop in value after the softcap, but is only beaten by strength, block value and hit (assuming not melee or spell hit-capped, but more on that here). I'd recommend just perusing the MATLAB thread; there's a wonderful table of contents at the beginning for the latest info.

Every point of expertise reduces the chance for the boss to dodge and parry by 0.25%. Boss's have a 6.5% chance to dodge and a 14% chance to parry.

So before 26 expertise (soft/dodge cap, 26*0.25=26) every point of expertise reduces the chance for the boss to avoid your attacks by 0.5% (0.25% dodge + 0.25% parry). Once past 26, expertise has no effect on dodge (as the boss has zero chance of dodging now) so every point only reduces the boss's chance to avoid your attacks by 0.25%.

Code: Select all
Exp   Dod    Par  Total   Diff from previous
16   2.50  10.00  12.50   0.50
17   2.25   9.75  12.00   0.50
18   2.00   9.50  11.50   0.50
19   1.75   9.25  11.00   0.50
20   1.50   9.00  10.50   0.50
21   1.25   8.75  10.00   0.50
22   1.00   8.50   9.50   0.50
23   0.75   8.25   9.00   0.50
24   0.50   8.00   8.50   0.50
25   0.25   7.75   8.00   0.50
26   0.00   7.50   7.50   0.50
27   0.00   7.25   7.25   0.25
28   0.00   7.00   7.00   0.25
29   0.00   6.75   6.75   0.25
30   0.00   6.50   6.50   0.25
            
54   0.00   0.50   0.50   0.25
55   0.00   0.25   0.25   0.25
56   0.00   0.00   0.00   0.25



The important thing is that it reduces them both at the same time.

Ah, ok, that explains it. Not an aggregate roll in other words. I wrongly compared it with how avoidance (miss + dodge + parry) + block + unmitigated hit was handled.
