First off: thanks to all of you who have responded and continue to post in regards to this issue.
From the responses you have given, I now understand the mistake I was making, So I'll offer my own explanation of why I was seeing the number's I was seeing.
I disagree that there is only 1 avoidance stat for druids.
Arent ther 4 total avoidance stats? :
Miss (gained from defense)
all of which are additive and share separate cap's + diminishing returns
Druids only get Dodge + Miss
DK's only get Dodge + Parry + Miss
Pallies + warriors get all 4
Among these, the avoidance stats are additive
if you had 50% dodge + 50 % parry you wouldn't get hit at all (in theory anyway)
and obviously having 100% avoidance would mean stamina, armor, etc, wouldnt really matter. So we can also say that as you approach 100% avoidance, the values of other stats such as stamina become less important compared to the next points in avoidance.
I think perhaps I see the nature of the confusion.
My example involving a 10% parry gain at 0% parry, vs a 6% dodge gain at 50% dodge shows 10% parry is definitely better than 6% dodge.
The confusion lies within comparing a single avoidance stat, against total avoidance.
in the parry example
0 ->10% parry gain = 10% total avoidance gain
50 -> 56% dodge gain = 6% total avoidance gain.
0 -> 10% total avoidance gain is, however, much inferior to 50 -> 56% total avoidance gain.
the reason the 10% parry gain is better is because it is much greater total avoidance gain.
Thus I think both sides were correct.
Side A: As total avoidance increases, additional avoidance stats become worth increasingly more, relative to the other tanking stats.
For example, if you're going to take 100% of the hits, you better have a lot of stamina so that u dont die right away, but if you only take 25% of the hits, you can afford to have much lower hp.
Side B: However, it is also true that as a particular avoidance stat increases, it receives diminishing returns, thus causing any other avoidance stats to become much more important, for example at 50% dodge and 0% parry, a 10% parry increase is much more
valuable than a 6% dodge gain.
With a warrior, having 4 avoidance stats, we would certainly note that parry, block, and defense become much more valuable than dodge, if we have an exceptionally high dodge chance, and exceptionally low block, parry, defense. Also because the avoidance
is split among so many stats, we might even expect that if all avoidance stats are low, as we increase one particular avoidance stat, we see the value of that stat drop not only in relation to the other avoidance stats, but to other tanking stats as well,
such as stamina.
With a druid, who only has 2 avoidance stats, as dodge increases by a large amount, defense increases compared to dodge, however because defense offers so little avoidance for a druid, it can be hard to notice this relative change.
When I go back to my earlier numbers of relative stat values:
RSV With Stam trinkets
With Dodge trinkets
If I add in the defense values:
the value of dodge increased by 1.39
but the value of defense increased by 2.03
so where I expected high dodge values to decrease the value of dodge, it actually is decreasing the value of dodge, only in regards to defense though.
And since the rawr data verifies this, I believe Char and Astrylian mis-spoke saying that dodge is the only avoidance stat for a druid, technically defense counts too :p
Thanks again to all for helping me understand this, and I hope this explanation is helpful to others as well. :)
