There are three power stats - Melee, Ranged, and Sorcery. These stats, coupled with weapon Melee/Ranged/Sorcery DPS, directly affect the power of most abilities in Eldevin.
Melee - Templar, Warrior, Assassin
Ranged - Ranger
Sorcery - Mage, Prophet
Classes in the same category have great synergy because their talents and abilities make use of the same power stat. Mixing classes from different categories is generally a bad idea when the talents make use of different power stats, because it means that both sides are less effective if you invest in two power stats instead of concentrating on a single power stat. Of course, there are talents in some of the talent trees that aren't tied to a stat, so those talents would be universally useful.
Notable exceptions are the Templar and Prophet trees. The Templar tree has threat-increasing talents and the Prophet tree has damage reduction and percentage-based healing talents which are useful for builds.
Recommended with this build: All attribute points in Melee or most points in Melee and a few points in Vit, heavy armor, two-handed weapon, essence with melee rolls if possible. Sorcery rolls also acceptable.
From what I can see, this build is meant for AoE farming and meant to be self-sustaining with heals.
The build isn't bad, but it isn't good either. I have some things I'd like to go over in your build.
1. Prophet tree doesn't have much use in your build
- Expunge - A warrior's main advantage over the other classes as an AoE farmer is the low AoE skill cooldowns. If the warrior is squishy enough to have to rely on the damage reduction from Cauterize/Expunge (which has a 60-second cooldown), then that negates the warrior's advantage and you'd be better off playing as a mage.
- Focused Healing - Focused Healing's description isn't accurate. Instead of directly increasing the amount that spells heal by 5/10%, what it does is it increases your Healing Power by 5/10%. Spell Healing = Essence DPS + (Healing Power / 16). This means that the Focused Healing talent is next to useless for characters with low Sorcery. As a warrior whose Healing Power comes mostly from having an essence equipped, this talent doesn't do much for you.
- Infused Healing - While in combat, Revitalize isn't going to help because you won't be able to outheal the damage taken since Revitalize has a 2-second casting time. If you're going to heal outside of combat, just cast an extra Revitalize to heal up instead of wasting 3 talent points here.
2. Bloodbath talents
I'm not too keen on using Bloodbath as a healing ability as there are too many drawbacks.
- The description says it deals 90% Melee DPS to up to 3 nearby enemies, but it's actually 75%.
- The targeting is buggy and it doesn't hit nearby enemies if they're too close or too far.
- The cooldown is too long to rely on it for healing completely.
- It only heals upon a critical hit, which means it's an unreliable heal.
- It only targets 3 enemies at most. A warrior should be pulling way more mobs than just 3, and while you're using Bloodbath to attack 3 enemies, the other enemies will still be attacking you. You take more damage than you heal. (If you don't want to pull many mobs, playing something other than warrior is recommended. Try a ranger or mage since they can attack from afar.)
- It requires too many talent points invested in it to even be viable for healing (and the heal amount isn't even very high).
Having said that, if you still want to use Bloodbath to heal... you might as well go all the way and grab Sweeping Strikes and Blood Champion from the Templar tree, and Cleave from the Warrior tree. (You don't have Sweeping Strikes in the build.)
3. Warrior talents
- Destruction is definitely the best single-target talent for a warrior. I suggest getting it before you get Swift Execution.
- If you're dropping Prophet talents, grab Blood Lust and Frenzy from the Warrior tree as well.
Possible suggested build based on what I think you might want: http://talenttheory....D1E2F2G1H1L3V1/
There's also Inspiration from the Templar tree to consider.
