It sounds like you want to play a p/w.

P/W is a jack of all trades type of class: not the best tank, not the best dps & not the best heals, but able to perform all 3 duties to an extent. Think of it as a melee class that can heal a bit. The main skills that you want tp in would be:
1. Battle Monk Stance - adds up to 56% pdef, 14% patk
2. Power Up - adds up to 45% pdmg, 15% hp
3. Ascending Dragon Strike - 30 rage, 600%+ main hand dps & +20% crit rate when fairy is up
4. Explosion of Fighting Spirit - spammable since it just consumes a little mana, 300%+ main hand dps & 600%+ main hand dps when fairy is up
5. Condensed Rage - 25 rage, but it triggers an auto self heal when hit. effect has 30 sec cool down from the last hit that triggered it
6. Regen, Urgent Heal - main heals other than soul source
7. Bone Chill - I use it to pull & in the melee fight as a our version of the bleed
Warrior Side skills:
1. Whirlwind - becomes our 1 priestly AOE
2. The passive strength bonus - max it out
3. Berserk - take it up to 30% to get +30% patk & sacrifice 30% pdef
4. Slash - add tp as necessary, it's a main skill early on until ADS since that's your main rage dump from there on; also good to use w/ bone chill to bleed gates
Pretty much, get the best axe you can for your level & tier it up well. Up to lvl 55, stick w/ healing gear but stat it as a warrior/tank... your main stat of choice will be any x/patk. Other stats that help w/ patk: str is 0.8 & int is 0.5. Holy Source gear has the best ROI early on since it plusses pdef/mdef fairly high. Later on, I would switch to Mage gear for the ghost int stats & from the set bonus. There is no p/w specific set gear, so we gotta do what we can.
The bonus to using mage gear would be the ghost int stats give us 2x matk, 0.5 patk. More matk = better heals & the 0.5 patk helps w/ bms. The main Runes you'll want are: Madness - patk/int, Block - stam/pdef, potential & enlightenment - +all
Main pet for this class would be a Holy Light pet w/ Sabretooth overlaid on it.
Hope this helps!
