Antitrust said I should write my build, so I will. It's different from his, in that mine is entirely melee and normal attacks dependant. It uses buffs and foregoes active-usage combat arts entirely.
Skills used in my build are similar, the order differs a bit. I don't take Focus or Lore skills for obvious reasons. Even making the effective level of one or both buffs slightly better would not be worth the skills points spent.
Skills taken and general order:
Sword Weapons - 1
Tactics Lore - 75+
Dual Wield - 75+
Armor Lore - User choice
Concentration - 1
Constitution - 75+
Warding Energy Lore - User Choice
Enhanced Perception - User Choice, though I recommend 75+
Toughness - 75+
Combat Reflexes - 75+
Sword Weapons is taken first, it fulfills 1 point of the requirement to unlock Dual Wield, and allows "Modifier Sword Weapons" bonuses to be active.
Then Tactics Lore fulfills the rest up until Dual Wield is unlocked, with 4 points in Tactics Lore.
After finally unlocking THE main skill of the class, take Dual Wield and keep it at character's level. I recommend keeping up with Tactics Lore as well, since this build relies on sheer damage.
Armor Lore should be taken next, not for the regeneration penalty, but for the +% to armor total, which helps significantly for a melee character always in the fray, so to speak.
Concentration is taken next, and kept at 1. The Mastery bonus is unneeded, since BeeEffGee diverts from the purpose of a melee build (and goes into ranged weapons territory), the regeneration bonus is similarly not needed. Taken at 1 still unlocks a second buff slot. At this point you can start using both Battle Stance and Warding Energy together. Before this point is reached, I suggest going with Battle Stance only. Enemies should not prove too challenging at the start either way.
Constitution is taken next for the HP, up until it is Mastered, then it offers its real bonus: Regeneration during combat. No need to get it very high up until Mastery can even be envisioned (around lv 60+).
Warding Energy Lore is next. It can also help with Divine Protection, probably the only skill used, because its very long cooldown is not a hindrance when it is needed sparingly (against groups of champions, or mostly bosses). It primarily helps with Warding Energy's buff though, where it gives nice bonuses to damage reduction. Both the buff and Divine Protection can be used in conjunction, though the latter will last a short time.
Enhanced Perception I take as 8th skill, at level 35, primarily because levels start becoming slow at this point, and the player would do well to get more decent equipment for the upcoming battles. Before it reaches Mastery, it still can help by being the modifier for certain things like Experience per kill, and Chance to find valuables (on equipment). Similar to Constitution, it should be Mastered as soon as possible, but it can be kept as 1 until then, boosted only by the orbs/relics.
Toughness provides added oomph to Seraphim's already very potent armor total, multiplied by Armor Lore's modifier, so it's important to get Armor Lore higher as well to benefit more from this. Previous to this (lv 50), a Seraphim should have pretty decent armor.
Combat Reflexes adds that nice final touch of boosting evasion and reducing chance of critical. It's not fully necessary, and can be paliated until then by forging runes with "+% evasion" into slotted equipment. Afterwards, slots can be used for other things, like Damage Mitigation.
--------------------
For the unique mount, given this Seraphim doesn't benefit from Combat Art regeneration, I warmly suggest the "basic" one, that adds defense and evasion instead of reduced cooldown. The movement speed is also welcome. Chances are, if you're careful enough, you might never need to buy a mount again. A Seraphim can be *that* strong. I wouldn't tempt fate and play hardcore mode my first time around just to prove my point however.
I would avoid horses prior to getting that unique mount. Because simply, Battle Stance is that important, and buffs do not stay when mounted on a horse. At an effective level of 18.1 of Battle Stance, it gives +170% or so attack and nearly +120% defense (and a hefty +150% regeneration time).
So this build relies entirely on hitting fast and killing quickly, taking very little damage. Equipment that reflects damage seems to work independantly of evasion (or maybe I'm seeing things), so even with capped evasion, you would be able to fight hordes of monster and see them become corpses before you even hit them. This build is well-equipped to fight many enemies at once, but ill-equipped against ranged fighters. Be advised of this flaw, especially in pvp (as in pve, ranged fighters typically don't run away for long). The buff BeeEffGee can be upped to be efficient, but without Ranged Weapons, the accuracy will be low.
What else is important with this build, is putting runes in the ever-so-important Battle Stance and Warding Energy buffs. Can also spare some for Divine Protection. For completion's sake, you can put all the other Combat Arts at 1. The rest I suggest using for forging into slots, or trading for Battle Stance and Warding Energy.
Once Dual Wield and Constitution skills reach 75, this build becomes extremely efficient (double hits and regeneration in combat). Once Enhanced Perception reaches 75, even better for the items.
Mod your two main buffs as you see fit. Augmenting the attack of Battle Stance is pretty important for accuracy, the rest is pretty much open to preference. You will get mods for Exalted Warrior by putting points in Dual Wield amongst others, so they will be acquired naturally.
In my personal build, Dual Wield reaches 174 at level 200. Diminishing returns make any investment above ~150 pretty wasteful, but this being the main skill of the build, and double-hits being pretty important, it is the highest. Most skills are left to preference as for their level. Armor Lore mastery isn't all that important, but a high skill level always helps.
