Doesn't help me out much, because A) I don't really understand much of
it, and B) it is discussing classes which have time+ gear and full
defensive AAs and worse C) it doesn't include Berserkers anyway, not to
mention D) it doesn't include bards either, so I can test the rumor that
bards and clerics are on a different table than warriors and knights.

Further, the classes weren't at even close to the same AC, I'd think it
would have been a simple enough matter to control AC by stripping off
some gear and by using Faith instead of Virtue so you could add or not
add Ward of Gallantry.

Then some classes had defensive augments and some didn't.

Ideally, this should be done at 100 AC intervals from 1K to 2K AC for
each class, in each case using characters as close in gear/aa as feasible.

Then, taking a character without a given AA, getting him that AA, and
trying it again at the same AC, deliberately changing nothing about the
situation but that one AA.

The way this test was done is a lot like taking all the people in an
elementary school, sorting them by race and height, and then making
conclusions about the connection between race and height while ignoring
age and diet.

Still, I'll give this a shot:

Progression
warrior
monk
Paladin
shadow knight
ranger
rogue
beast
cleric
shaman
druid

Plate melee plus monk, chain melee, beastlord, then priests again in
order plate, chain, leather.

Odd man out is the monk, who is in the middle of the plate classes for
some reason, despite a nerf that I'm told put him deep in the priest
regions.

Of course the problem is that he takes damage like a warrior but has HP
like a druid

Still, back to berserker.  I'm looking over the chart trying to see
-why- the order is the way it is.  It looks to me as though it isn't
about any one thing, its about all of them added together; or rather its
about mitigation and avoidance multiplied together.

I don't know what the mitigation of a berserker is, but the avoidance
should be relatively easy to find; looking at the chart this seems to be
the result of block dodge parry riposte... and some other factor I don't
get, which shows in the miss% column (which apparantly factors out the
above).

Various classes seem to score in those areas just as you might expect by
their skill caps in them, with NA where they don't have a skill.

OK, Berserkers have dodge, parry, and riposte, with caps of 175, 175,
and 225; they lack block entirely.

Is the Miss thing based on Defense?  Berserker defense cap is 240

And from there I'm really lost.

Grage, 55 Berserk, Luclin
Warrior
Monk

Well I would like to see a little more info with people using at least
similar AC values. Though from personal experience the BST at 1400 AC seems
pretty low, since mine at level 51 is at 1100 AC with self bufs. (A little
twinked but nothing like I would assume time gear should do)
I am assuming the tests where the same guard, so there was no level changes
etc. Maybe do this a little more controlled vs. a caster's pet in a duel or
just a duel vs. a level 65.

Course I am not volunteering to take the time to do this, and I applaud the
person who did the test, just suggesting alternatives :)

Ok - everything except the monk one makes sense
from the steel warrior parses.  In those they
had a 1300 AC monk (no shld/avd) and 1300 ac
ranger (no shld/avd) take approximately the same average hit
(although the monk avoided far more).  Is there
more than a subjective feeling that supports that?
