As some of you may know, I leveled my Engineering to 375 on the PTR a couple of months ago when they patched the epic goggles into the game. Since that went live I haven't really been trying too hard to level up again, Blizz bummed me out when they added Primal Nethers to the goggles and I had no motivation to skill past 350 on my level 60 toon.
But I've actually been playing that toon lately (Kayree, a tank) and she's a sneeze away from level 63 now. Not that this puts the goggles into easy reach for me or anything, but I thought I'd suck it up and make the push to 375 since she was sitting at 371 just from random combines I did for my other toons, making bullets for cash, etc. So I sat down and calculated the mats for 5 felsteel stabilizers and mailed ingredients back and forth (Kayree does not have mining) and cranked them out. And got 2 points...
Ok, so that wasn't such a hot plan. I decided I'd better just bite the bullet (rofl) and make a couple of the Adamantite Rifles that were still orange. I actually had most of the mats for one in the bank, I make a point to grab those engineering parts off the Netherstorm vendors when I happen to see them. So I bought some thorium and made myself a second tube and I got a skill point for one rifle. To make a second rifle I had to buy the components off the AH, but at this point it seemed stupid to stop at 374. And now I'm officially 375 in Engineering. Again.
Since Kayree is a gnome I can go all the way to 390, but it will involve making lots of Ornate Khorium Rifles which I'm not looking forward to. I did go ahead and buy the recipe though, just so I'd have it whenever I decide I'm ready to waste a lot of money for no good reason. I also went ahead and updated my Engineering guide on Crafter's Tome with the BC info, although Kayree is still too low for the new transporter gizmo. I bravely ventured to Toshley's Station this morning and found no one who would talk to me... guess I will try again when I'm level 63.
So here's how the 350-375 grind played out for me:
350-365: Mostly White Smoke Flares cuz they are cheap to make
365-370: Miscellaneous Parts (Felsteel Stabilizer, Khorium Power Core, etc)
375-375: More parts and 2x Adamantite Rifle (don't waste time on parts like I did)
