This is my first build ive made that actually works efficiently, so please dont flame me too much but feedback is appreciated

Profession:
E/Me
Attribute:
16 Fire (12+3+1)
10 Energy Storage (9+1)
9 Water
Skill Template:
1: Arcane Echo
2: Mist Form (E)
3: Glyph of Lesser Energy
4: Meteor Shower
5: Flame Burst
6: Phoenix
7: Lava Font
8: Fire Attunement
Equipment:
Armour doesnt really matter.
Weapon i use an Insightful 20/20 Staff with +1 20% Fire Magic.
*20% Enchantment Wrap is a possibility if you want to drop Water to 6 (13 Seconds) for an extra point in Energy Storage, completely upto you.*
How it works:
From Droknar's forge leave for Talus Chute and head North West to the Troll cave. If any Avicaras are there, try go around them. If they aggro, just run upto cave entrance and they will leave you alone.
1: When at cave entrance cast Fire Atunement then Arcane Echo.
2: Run into cave and aggro all the trolls there, wait for them to get close and Cast Mist Form.
3: Cast Glyph of Lesser Energy, then Meteor Shower, Flame Burst and Phoenix.
4: Your Mist Form will be about to end so cast it again from the Arcane Echo.
5: As the Trolls disperse, large groups will run back at you, as they do, simply cast your recharged damage spells as they get close.
6: If any trolls are left, simply use Mist Form again and finish them off.
Possible Problems:
Only problem i have is when Avicara are very close to entrance to cave. You can take out Lava Font and replace it with Windborne Speed to get past them BUT when fighting the trolls you will have to run away on a last couple using Windborne Speed and wait for Mist Form to recharge before going in and finishing them off. Its best to /resign if you get a terrible spawn.
This aint anything special or groundbreaking, but its a pretty fast, effective and different way to solo farm trolls for those without 55's.
Happy Hunting!
