Over Training in Armor Use
In addition the Armor Specialization List, we have implemented an additional benefit to continuing to train in the Armor Use skill: For every 50 ranks of Armor Use that a player has above the minimum ranks need to train away the RT adder for their armor, their armor's Action Penalty will be reduced by (Armor Group - 1), a maximum reduction of 50% of the original action penalty.
For example, an augmented breastplate requires 90 ranks of Armor Use to train away its RT adder. It has an Armor Group (AG) value of 5 (skin = AG 0, robes = AG 1, soft leather = AG 2, hard leather/scale = AG 3, chain = AG 4, plate = AG 5). Its base action penalty is 25. So, if it is worn by a player with 140 ranks of Armor Use, the action penalty will drop to 21, to 17 at 190 ranks, and to a minimum value of 13 at 240 ranks.
This benefit is available to all professions.
Armor Action Penalty
The Armor Action Penalty is a relatively significant factor. For a character exactly trained for full plate at cap, it contributes a penalty a little bit above the difference between 1x and 2x PF. Overtraining in armor to reduce the action penalty and/or using Armored evasion can reduce the maneuver penalty by a fairly significant amount, however.
I do vaguely recall that but I can't find the specific post to see if I was actually right or not (gee that's helpful, eh?). So let's ignore that and just go with this:
Armored evasion adjusts your Action Penalty for more than just your DS. Other things that consider include (but are not necessarily limited to in case I'm missing something) Spikethorn, Quake, Roa'ter Burrows, SMRs, Boil Earth, Lava Golem blob attacks, and Minotaur Charges.
<<Ixix, Thank you for confirming that Armored evasion is useful for dodging maneuvers. Maybe that means people will take us rogues up on offering Armored Evasion. Is there any way you could confirm how the formula works? I would prefer not to train in Armored evasion if it doesn't give me any benefit for wearing brig.>>
The formula on the wiki is correct: (Armored Evasion Ranks * (7 - (Armor Group)) / 2), the only other catch that I see is that the reduction can't take you below an AP of 0.
It works as a direct reduction of your Action Penalty (for those things that take it into account that I mentioned earlier). Taking brigandine for example - you have a base AP of 12. Your Armor Group is 3 - with say, 3 ranks, you'd get a (3 * (7 - 3) / 2) reduction for a total of 6, reducing your AP to 6. If you were in Metal Breastplate, AG 5, you'd get (3 * (7 - 5) / 2) for a total of 3 reduction (from 20 to 17 in that instance).
That Action Penalty value then goes on to factor into those various things in different ways, but the closer your AP is to 0, the better.
The wiki lists APs as a negative value, these examples are just using the absolute value in case anybody is confused by that.
For those of you who weren't at SimuCon, there is going to be a change to Armor in the future to where there will be a benefit to over training.
In so far as the change goes, Ildran said that they were looking to focus more on the agility of Rogues, in that over training in armor would allow one to "roll with the punches" more... which equated to damage and crit reduction, if I remember right.
But, before someone starts screaming about how they don't want to spend TPs and over train in armor for these bonuses...
Ildran also said that the armor ranks that you have (read; Train in 30 ranks for brig and stop) will count towards these new mechanics. You will still see these benefits, but at an extremely reduced rate (compared to someone wearing brig with, say... 130 ranks of armor).
Warriors, of course, will have more benefits/options, as Armor is more of a "core skill" for them.
Thus, this potentially falls under the "Rogue love" category.
