Yeah looking at it ive got the Unleash elements bit wrong, i thought it made it an instacast, u can see how much ive used it
Now that i know it makes your next heal 30% more effective i imagine you could be using it just before you use natures swiftness when you know thers large amounts of tank damage incoming so that you get a huge heal off instantly when the tank gets smacked.
As for Telluric Currents the pro's like Kahva from paragon all use it but i prefer to have the movement buff because it means less time in fire and is useful on fight such as valiona and theralion where moving quickly is esential. Telluric Currents is good for mana regen but i find now that i have 2k spirit im good without that extra mana regen as long as i MTT early enough. As for focused insight ive never used it and although it does increase healing and reduce mana cost i'd rather not have to worry about smacking the boss. The mana decrease i will have to look at because im not sure what 10% of the shock spell's mana equals yet.
Im using the elemental weapons and improved shields talents in the enhance tree because im not using TC which means i dont need the hit from the second tier of Ele talents so i have 5 spare talent points to chose between the enhance and ele 1st tiers and the enhance seem better because they give Mp5 and make ELW give 40% more spellpower.
