Guild Wars 2

I’ve been running an Engineer since launch. I’ve tried other classes but always come back to my Engi. It’s by far my favorite class.
In the beginning I spent a ton of time and made many adjustments to dial him in just right. I finally got to a point where I was happy. I was blasting through PvE. After full map completion I moved on to WvW. I made some adjustments for that and again found a place where I was happy. Believe it or not I have been running the same build with little change for well over 10 months with great success in PvE and WvW alike. Lately something has changed though. I’m still fine in PvE but struggling in WvW and think it’s time to make a change. I’m ready for a full overhaul if need be but would like peoples input. This is my build. For Traits I run 4,6,4,0,0.
In Exp line in have shrapnel and incendiary power.
In Fire I have sitting duck, rifle mod and modified ammunition.
For Inven I have energized armor and power shoes.
I run all Exotic Kinghts armor. I know most of you will laugh at this but I’m still using Ruby Orbs in my upgrade slot. The way I see it I’m getting 120 power, 84 precision and 84 ferocity. I know they took a big hit when critical damage was changed to ferocity so to compensate I got the Stonecleavers Musket which added 134 back to ferocity. My Sigils are bloodlust and force.
My power is 2,228, toughness 1,595 and precision 1,810. I typically run Bomb Kit, Elixer U or power goggles and always rocket boots.
I never roam alone in WvW, I prefer medium to large groups. I want this new build to be centered on WvW zerging.
I log onto this forum every day and read everything about Engineers. I have seen many people post builds. I know the topic of WvW builds have come up many times but I’ve never seen one so much better that I felt I must copy it. So more than anything I just want people to look at this and make suggestions. I hoping to just be able to fine tune it but if that is not possible I am will to make full changes. As I said the past month or so I’ve been getting my butt kicked in WvW and I’m tired of it. So please critique away. I’ll make any need changes. Thank you,
