I am currently playing my engineer. I got the daily Wizard's Vault objective to perform 3 combo skills in combat. As I try to complete it, I am having no success. So, I look at my weapons. I currently have three builds using Rifle/Mace/Pistol, Pistol/Shield/Pistol, Pistol/Shield/Rifle, well guess what, zero combo fields on any of those weapons. The specialization for Mechanist has zero combo fields, it wasn't until I got to my fourth build did, I had a single skill that had a combo field, my Scrapper build had the skill Function Gyro. Having just one single skill is woefully underrepresented for the Engineer class. Now I am not going to spend my valuable time looking at all the classes to see what they are lacking, that is ArenaNet's job. But I wanted to make a strongly stated suggestion that needs to be fixed. People should NOT have to spend their time looking around for builds that meet the Criteria, every weapon should have at least ONE combo field.
