Doomlore shrine issues

I am having severe issues with that dungeon there. I have a D/Mo and I can't seem to get past the first level of the dungeon (I am such a looser!). anyways I am wondering, I read some where on the GW wiki that there is a place in one of the 3 campaigns or on the expansion that you can buy all non elite skills....

Where is this this place, because i am thinking that since I havent upgraded my skills in a while, that if i buy some new one, get some new armor i may have better luck.

So wheres this place I can buy all the skills except elite skills (note: they should sell elites skills)

Prophecies: Ember Light Camp
Factions: Harvest Temple
Nightfall: Gate of Torment
Eye of the North: I'm not sure, but I'd imagine Rata Sum.

Each of the skill trainers have the respective campaign and core skills only.

I assume you mean Cathedral of Flames. Armor should only be a problem if yours is less than max (70 AR). If its not, you need it. For dervishes, Windwalker insignias are reccomended because Dervs are almost always enchanted. Also i have never heard of this place where you can get all non-elite skills, but there are places in each campaign. In Nightfall, all non-elite dervish skills can be bought in the Gate of Torment. In eye of the north, just go to Gunnar's Hold to get the eye of the north dervish skills.

The main reason you are failing is probably not you, but your party that is bad. Try getting some good builds for your heros. Heros are a vital part to a team because they can be customized. Good builds can be found at www.pvxwiki.com, or here on guru in "The Campfire". If you are still having trouble, try going with other people like members of your guild.

Thank you for your help

Do you use Avatar of Balthazar for your holy damage? If so you should take a sunspear skill that you can get in Kamadan and its called Eternal Aura. It gives holy damage upon activation and after 10 seconds it recharges all dervish skills, so you dont have to wait 45seconds for the avatar to recharge. http://guildwars.wikia.com/wiki/Eternal_Aura

Or get the more important PvE skill: Aura of Holy Might. Get it. Best skill you could use. Avatar of balthazar is fail, use lyssa, melandru, or wounding strike.

Melandru's for CoF since the foes like to spam blind and weakness With Eternal aura and AoHM you will do great damage.

Eye of The North guy has all the skills available in EotN.
