Anet really needs a design focus for the Engineers and they really need to look no further than their own lore AND representative for the Engineer class: The Charr.
Engineers need a design goal. Look no farther than the Iron Legion
On the Asura:
The engineer is a tech-based class based on Charr technological advances. Outright magical effects on the Engineer are fairly minimal; in fact I’d argue that since the Engineer is the only class that doesn’t have any sort of signet, it’s the class that’s the least reliant on magic. This means that Asuran technology, which is magic based, can be put aside until an expansion allows magic-based technology (or magitek) to be more fully fleshed out. Right now, focusing on Charr efficiency and reliability would be in the best interest of the class as a whole, eliminating the stereotypical “bumbling tinker” and “mad scientist” archetypes that are holding the class back. It’s because of this split attention to cover as many of these archetypes throughout other fiction that Engineers are failing so hard, as opposed to just using their own in-universe example.
In short, too much Goblin/Gnome WoW style engineering. Not enough Charr GUILD WARS lore type engineering.
The Iron Legion
It’s easiest for me to explain how the Iron Legion functions in regards to how it works in tandem with the Blood and Ash Legions in the Iron Legion personal story. It goes like this: If the Ash Legion controls fights through information and sabotage while the Blood Legion does the heavy lifting by damaging enemy forces, the Iron Legion would be the support that supplies the other two with what they need. While not a perfect representation of the Thief and Warrior, I’d argue that support is the direction that Engineers should be focused towards rather than this crappy “Versatile, but not as versatile as Elementalists” position that they’re in.
Anyways, in the story, your character develops the “Ghostbore musket,” a firearm in terms of Engineer traitlines. However, later on in the story you’re asked to supply your ghostbore prototypes to either the Ash or the Blood legion, both of whom are trying to argue that their legion will put the tech to better use.
This is important! Here we essentially have a Thief and Warrior fighting over who gets to have the most Engy support! They want us because we have the tools that allow them to perform their jobs better! And that’s not all. While the Iron legion has the most engineering tech and comes up with the base designs, the other legions also have engineers that adapt the ghostbore musket into a turret and cannon respectively to suit their roles. If the ghostbore musket is a firearm based kit, this means that those engineers are taking a Firearm base and changing it to work with their Invention traits or Explosives traits.
If the Charr race is the class that represents the engineer the most strongly, why is it that Engineers don’t have this kind of adaptability? When an engineer traits for deep elixirs, he basically has to use elixir utilities or waste an inherent bonus of the traitline (boon duration) because hardly any other utilities grant boons. An engineer has to trait specifically for grenades if he wants to get any use out of them at all. This is totally backwards from how they should be behaving in-game and lorewise. An Explosives Engineer with only Elixir utilities? No problem! Now you have an Engineer throwing Explosive elixir bombs at enemies that happen to buff allies that they come into contact with. We need condition removal, but our Alchemy engineer brings only turrets! Oh wait, an alchemy based engineer has turrets also shoot condition removal bullets in addition to their normal attack.
