Guild Wars 2

Looking for >>Real non-super-pro-dodging-Pattern-spamming<< Elementalist build with high dps and some survivablity so that I don’t fall everytime i do not dodge 1 or 2 hits from bosses or elite mobs.

1) MixCelestial Staff (2200pow/2500armor/14,5k HP) :

Which build would You guys recommend?
Also I have no idea how to calculate DPS – Is there a high diff between those?
Is it better to sacrefice a little bit of Power/Fero to get 300-500 more armor for surviveability?

I’m currently running on Exotic set (1,9k power/2,5k armor/14k HP) and it seems my damage isn’t that bad, but I am often last one standing in party thanks to the 14k HP and armor i think (since when playing with PUGs in Dungeons/fractals I sometimes survive with 800 – 1,5k – 3k hp).

Please help me pick which Ascended set should I create ^^
Thanks in advance! (p.s: I will be swapping to D/F at more difficult content)

First of all d/f is more defensive then staff, just earth#5 saves kitten so much. Then air#4 for projectiles.
Given the fragility of the ele active defense is really the only solid options (skills, boons, dodges) so build to havee them.
My suggestion therefore is d/f full zerk.
Maybe with HoT condi will become more usable raising rabbid or rampager/sinister but zerk will always be good option.
As of build i run fresh air but that’s up to you.

Mi 2 coppers ^^
