Guild Wars 2

I currently am working on making 5 characters 100% PvE and am on the home stretch all with 90%+ completion im working on my final builds for each profession and Engineer is making my head hurt

I was thinking about going Pistol/Shield however i feel like Pistol/Shield is not the best build if I am going to build Condition damage (rampagers/carrion havent decided) But i also like the aspect of being able to survive well with the toughness it takes to trait your shield.

Along with those concerns i dont know what i really want as Utils, as an asuran i usually go Technobabble, and Radiation field for the fact i can dodge into a zerg and lay area conditons with my f# skills. But without my shield this will become problematic as my 3rd utility i have been running net turret for the snares and Supply crate for another stun/snare along with increased damage.

Im wanting to try the 3x gernade kit along with conditions, im willing to lay down my shield and try Dual Pistols, but rifle is foreign to me 4/5 make it hard for me to learn it because they are positional skills good in certain postions

Let me know what you think I should do.
