So you want to do this the hard way.... fine..
**throws gauntlets**
HoH build = downright stupid unless you're main healing. You have half the DPS of LtC, but with a a shallow investment of 2 HoH traits, Now for Wrath and Relentless Optimism (assuming at least 20% tactical crit chance), my healing will be comparable to a deeper traiting in HoH.
See

With War Banner + LtC + Self Blade Bro, I do not doubt that a captain can break the 1.5k DPS mark, if not push higher.
LoM traits are completely pointless outside of tanking. The zero mark cooldown is one of the most overrated aspects of the class, and not worth the traits spent to get it. The three set bonus for LoM is useless in most stuff, unless you really need the threatening shout cooldown for off tanking - which most captains do not.
Defiance and Blood of Numenor are crutch traits that sacrifice the captain's contribution for the group for a (largely) unneeded safety net. Composure is meh, especially when you can produce enough of the defeat responses from a heavier red build, so you don't need to have the Composure swap emblem to achieve a similar amount of Rally Cries. Tactical Prowess is interesting, but not really worth it considering the set bonus compromises elsewhere.
Since the vast majority of captain skills are melee skills, you will want to have at least 3 red traits for the -melee skills power costs, which helps with power conservation in raiding. To help close the gap with a heavy red build for healing, you need to generate defeat responses by critting on DB and PA, so that means you will need Expert Attacks, Renewed Voice, and two more LtC traits so you can get +5% melee skills healing, putting melee critical chance at 25% (which is 1 out of every 4 hits, compared to 20% which is one out of every 5). Blade of Elendil and Battle-master will up your personal DPS, and hit they red mark.
At this point, you have a choice, either stick with the legendaries, and pick up either Fear No Darkness for better spot heals, or Deeds Before Words for better Inspire healing (which doesn't affect power btw), or sac a Legendary (IDoME is a good one, especially considering the DPS races in ToO), and Pick up MoW so you can generate even more Defeat responses, in addition to improving your DPS. That third blue trait will also give you -Vocal Skills power costs, which helps with power issues.
Throw in 3 Perserverance with a 2k+ might build and 25/20% crit, and you have a recipe for a lot of DPS, a lot of heals, and a lot of RCs.
As far as power issues, go, stack ICPR in your relics, pick up a 100 ICPR bracelet, and you should be fine, especially with a self Blade Bro.
