Engineers can ‘skin’ mechanical mobs, which gives a chance at Volatile Blasting Triggers, used in explosives and bullets. I spend an hour or two a week and farm all the Triggers I need for bullets at the airport in Borean Tundra. Incidentally, we make the best-in-slot Ammo in the game, with the alternative being Violet Eye Reputation ammo.

I’m a miner, but any gatherer will do as a good companion to engineering. There are many more clouds than there were in BC. More zones have them, and they seem to have more spawn spots. Also, more kinds of eternals come out of clouds than they did before. I’ve gotten all but crystallized life out of cloud spawns.

We can make some pretty stellar scopes, and they’re cheaper than Attumen’s or even Biznick’s were. +40 Crit (any), +40 Haste (mm/sv), +15 dmg (cheap). Potion injectors are far better implemented this time around. You craft a 5-stack of BoE items, which combines with 4 stacks of potions. This way engineers no longer have to craft them for others, and we can sell them on the AH without investing in potions.

The rest are really just perks, like freeing up some bag slots with the pocket knife, having a cheap portable vendor, portable mailbox, repair bots.

Gnomish and Goblin engineers didn’t get much differentiation. And there’s no Teleporter yet – though there’s a setup for it in K3. I guess they wanted people to take the Band of the Kirin Tor vs. an engy trinket. I hope they add this in an upcoming patch.
