Thanks for that very elaborate response.
A few followup questions:
What do you consider is "significant
"? I see a lot of debates here in these forums that x.x% DPS, EHP, Healing, Crit, Crit Dmg etc etc is significant. Is 25% significant? Is 12.5? Is 6.25?
How do you consider uptime? Uptime becomes more important when the fight lingers on longer, the problem is, most fights don't really last "that" long (sans a few boss fights, fractals)
How did you compute for the healing AH does?
What is your concept of "over-healing"?
What are the disadvantages of Sonic Boon? (since you don't really discuss it)
Now, the very first difference in the builds I see are that this is a Warrior build and that a Guardian build. The issue that arises here is that Warriors inherently have much more health than Guardians. About 8k more in fact, or 800 vitalitys worth. Considering our vitality isn't different by much, this causes you to be at a serious disadvantage (Especially with the lack of Omnoms).
While they are 2 different builds, for 2 different classes, they do arguably the same job, which deal DPS and support at the same time. While Warriors do have in fact, more health as guardians (base 18k vs base 11k I think), and I think the "disadvantage" is removed with the presence of protection and aegis. The visual builder doesn't consider these 2 in it's equation. Pies on the other hand are a different story all in all, that's why I asked you above on your concept of over-healing, as I found AH on it's own is enough to supplement a guardian's self-healing (every 3rd GS AA gives heals, as well as every proc of Strength sigil and Empowering Might [EM], and all the buffs you supply to yourself and the party).
You get self regen to match ours (When you add in the extra healing our 6 skill does more than yours)
Actually, Healing Surge heals for just over 300 more than Signet of Resolve (base, around 600 more with your build, which in return i ask again, is this significant?), not to mention that Healing Surge is Adrenaline reliant. We also have the passive in Virtue of Resolve, Regeneration from Hold the Line/Save Yourselves, as well as AH. I don't have math to support this, but I think guardian self healing is better (not by much), even without pies.
On might stacking:
I think that might stacking is fairly trivial on either Sonic Boon, or AH-EM guardians, as the number of enemies directly affect the number of mights you get on yourself. However, Warriors have automatically 8 stacks of might to work with (SoR/FGJ). Though once you're talking about hitting mobs (Whirling Wrath hits more opponents, and for more hits (7x2(?) hits opposed to 8) than 100b, which help empowering might), as the number of opponents go higher, we'd be looking at roughly the same amount of might stacks.
I'd also like to point out that you missed the usage of Staffs. Using Empower grants your party 12 stacks of might for over 17s (in this setup), given that Empower CD is reduced to 16s due to 2-handed mastery. Again it benefits from AH (you can go from 0% to around 100%hp depending on how much allies are hit with empower), and gives your party a base heal of 1200 (increases with healing power), Orb of Light while more of a crutch heal, is a heal on it's own. Symbol of Swiftness also grants your party 100% swiftness. There are other things you've missed as well, such as Virtue of Resolve (both passive and active effects), dodge healing, near permanent self vigor, etc.
All in all though, the biggest difference between the builds is their direct damage. We have much more than you between 100B, at least 6.5% base, ~15 more stacks of might, ~15 stacks of vulnerability (Buffs party dps too), etc.
Aside from the Vunerability, Whirling Wrath deals at least half the damage of Hundred Blades (the animation is gimped, and doesn't show the real damage most of the time), and as I said above, empower not only gives you, but your whole party automatically 12 stacks of might to work with. Not to mention that this specific build has 20% more critical damage than Sonic Boon.
The thing I like about the guardian is, that it isn't "pigeon holed
" into the build. AH guards have a lot of options both in traits and utility, as opposed to warriors. Banners are more or less inferior to shouts, and that's the only build your trait selection can really branch out to. A guardian can easily turn from AH Empowering Might, to AH Hammer Heal (while it does require people to stack, it gives the party near permanent protection and a ton of healing to you and your party mates. You can easily change your utilities/traits to match a certain event (need party condition removal? Get Pure of Voice || Wall of Reflection and Shield of the Avenger are a godsend in fractals and some dungeons).Warriors just don't have that much luxury, and in turn, versatility.
I'm sorry if I got a bit picky with my quotes, the ones I quoted are those I found a bit iffy, the rest I either agree with, or just don't have data on my hands to respond properly with.
My post also seems to be all over the place, just got off from work and fairly tired, so I hope you forgive me if some of it seem incomprehensible at times.
While I have graduated from using your build (gone GC, since I'm usually in organized groups now, I still have my Boon Duration armor though!) I'd still recommend it to the lot who don't have the luxury of re-rolling into a guardian, or don't have consistent organized groups to play with. I learned a lot from using your build, and I hope for others to learn something as well.
