The Chua Engineer's weapon is almost bigger than he is. It obscures most details of the armor. The presumed silhouette of the Engineer from the official site's class page appears much heavier. The "robot suit" might only be used for tanking, be a higher level armor look, etc. Correct. We should know later today if the following pattern continues. As member Ragx pointed out, and discussed earlier in this thread, the silhouettes on the class page are numbered. The Chua should be the Esper revealed later today. The Mordesh is labeled "class-unit class-5". Before Carbine fixed it, the bar above the silhouettes read Warrior, Esper, Spellslinger, Stalker, Medic, Engineer. In other words, the Mordesh corresponds to the fifth class.
