what about stats and armour?

full stamina, full hp, mix?

Definitely my class and playing style, I love it and I can say I'm quite effective according to other players .

I'm lvl 46 stamina templar orc with 2-handed greatsword, blue quality crafted gears, purple food and triple potions to maximise stamina pool and regen. 7 pieces heavy armor: 5 pieces from Vampire's Kiss set, rest 2 pcs. armor + greatsword/healing staff from Song of Lamae (giving extra spell and physical resistance). All armor parts with stamina enchantments and well-fitted trait. Well-fitted is great not only to better scouting without horse when out of combat, but more important - to run away from stronger enemies without loosing much of stamina, saving as much as possible for a quick run and Rush again to enemy from distance.
I also base on possibly high amount of critical damage, and have about 22-28% critical actually (extra crit damage from veteran hero points), however with strong [Critical Charge] making critical damage each time, it's only my personal choice.

Vampire's Kiss set (5 traits) is really great in PvE, due to it's wonderful healing, aplied on us after killing simply any creature around. We can start fighting alone with the boss and after his first damage we can roll back and kill any small creatures like spiders, frogs, or deer and we will be healed immediately in this 6 seconds period. And the healing effect stacks, so time of healing is elongated according to number of enemies we killed. I found it very effective to kill several (even 10-12) standard enemies together in close fight, by dragging their attention and killing them one by one at first to start healing, then following with strong aoe on the rest. Doing it completely alone obviously, so if you are in group this grind would be even faster.

Generally I prefer shadow mundus stone to increase damage from [Critical Charge] which is the most often used ability and it also guarantees that we can easily stay out of the influence of area effects or heavy attacks when we see an enemy going to do these. Especially fighting alone vs large groups of enemies, like in public dungeons, which usually consist of few slow moving knights, some bow rangers and sorcerers - best is to stay in move and to jump between enemies with [Critical Charge], aplying [Reflective Light] and [Cleave] from time to time. It kills the whole group very fast.

In main weapon bar I use first four offensive abilities from 2H weapon and one ability from Class - Dawn Wrath skill - Sun Fire.

My mechanics depends from the enemy, but for large groups (or groups that I create by drawing attention) I use:
1. [Sun Fire] morphed to [Reflective Light] to afflict 3 enemies at once and slow down those who are usually running at me.
2. [Critical Charge] morphed to [Critical Rush] to the closest one, then again same ability to another in range.
3. [Cleave] morphed to [Brawler] - usually in this time enemies already grouped near me, so I use [Brawler]+[Reflective Light] 1 or 2 times.
4. [Uppercut] if it's not a group but stronger enemy - morphed to [Wrecking Blow] to gain extra 20% damage on next [Wrecking Blow]
5. [Reverse Slash] morphed to [Reverse Slice] I use when I see nearby enemies on low health, so can kill a few in one powerful blow.

Generally my 2-nd weapon is healing staff and templar abilities, but since when I have Vampire's Kiss on me, I do not need the Staff abilities to heal - just kill any creature nearby and healing is automatic.

I successfuly checked my build today in dwarwen public dungeon in Bangkorai, where I could win alone even against double groups of enemies - the set's healing with [Cleave]+[Reflective Light] done a great job.
I recommend this to anyone who generally quests alone and wish to be strong enough and level faster, also almost every group boss can be easily soloed without asking for help .

PS. Vampire's Kiss Set is also fantastic for being a Werewolf - I noticed it works also after we change into WW form, constantly healing us, so no need for healing from WW ability.

Edit:
I currently level these champion points:
The Tower -> Warlord
The Ritual -> Precise Strike (to make [Critical Rush] stronger)
The Steed -> Spell Shield (to defend from range sorcerers, who are usually 2-nd to kill after knights).
