Hi i am here to explain the build i am using whit the Engineers and why i like it so much.
http://gw2.luna-atra.fr/skills_tool/?lang=en&code=3ekag0dpe7e6e8hfq0au0u0a3aaacaub6b7k8
this is the skill build link, Now ill explain, the build is base on Conditions, mean ill bead you to dead. but not only that i have different Way to do it.
i use Dual Pistols i decided to use my pistols Rampage, which have Power, Precision, Condition Damage.
and the Medium armor i use the Carrion set, Contain Power, Vitality, Condition Damage.
And my accessories, Neck, Rings Will be Rampage, which are Power, Precision, Condition damage.
Of course a pretty basic DPS build whit high survivability.
i decided to keep my pistols whit precision because whit my boons i can achieve 60% Critical chance. which i guess is high enough. my build is base on Elixirs a alchemy.
in other words kite and kill, on weponds i need the Superiors Runes of the Earth. because i need to apply extra bleeds on the enemy. also my armor use 3 set of runes different.
x2 superior runes of the monk
x2 superior runes of afflicted
x2 superior runes of the krait
i use them because of the Boon duration effect and then Bleed Duration to stack. and bleed longer.i love it since i been using it.
on my traits i have power at 10 which allowed me to apply burn per chance on crits, 30 firearms , gives me the Extra range on pistol attacks, then burn duration, and the Pierce shoots. which works SUPER great. also 30 on alchemy which make my elixir cool-down shorter, and the boons duration longer, and it make its almost spameable. also i have a Double trait that can be exchanged, i can Turn 5% of my Vitality Intro Condition Damage, OR get the 1 that will remove 1 condition for each elixir i drink. Both are great its all depends on the Situation your in.
Well i hope you like it and b useful Depending your playing style. :)
Thanks.-Hokaido
