Help Improving This Build

Hi, I'm new to guild wars and my first character I chose was Dervish. Absolutely love it. These are the skills that I'm running and I would like anybody to make suggestions to improve it. Thanks so much for your help.

Scythe: 15 (12+3+1)
Earth: 9 (8+1)
Mystic: 12 (11+1)

Skills:

Victorious Sweep
Wild Blow
Rez Signet
Avatar Of Dwayna
Faithful Intervention
Mystic Regeneration
Vital Boon
Conviction

Armour: Full set of windwalker insignias.

Use:

The idea is to stay alive as long as possible and absorb as much damage. When you first enter an area cast Faithful Intervention. When u are about to start a battle cast Mystic Regeneration, Vital Boon and Conviction in that order. Cast Avatar Of Dwayna beforehand if necessary. Find a target and swing that scythe using Victorious Sweep as your attack. If they have a stance that is blocking your attack use wild blow, especially on Whirling Defense. When your enchantments run out you should get a huge health bosst, but as soon as you get it recast the two enchantments again and conviction as this will run out shortly after the enchantments. There should be no problems with energy management due to the energy you get with mysticism.

Problems:

There is no way to remove conditions using this and blindness and daze is very annoying. If anyone could help me it would be much appreciated.

I would drop dawanya for reaper's. vital for mystic vigor. and perhaps victorious sweep for chilling victory

what he said -- more damage plus you still get up tpo +25 health for each foe you hit and with Victorious so long as you have more health than your foe you can healed up to +83 for each target struck....not to mention the monster health regeneration from mystic regen
