I seriously checked the year this thread started
multiple times in confusion. Because it's clear you guys have an entirely different engineering experience than I.
1. Linking old 70 goggles is kinda useless. I doubt they're even worth making if you own WOTLK. Level to 80 and get better gear.
2.
Greensight Gogs are not ideal for any spec but Balance.
3. Greensight Gogs are inferior to a
Heroic Blue item. This is a far cry from the level 70 goggles which were the best head gear you could find til higher end raid gear (basically making them the
primary reason you would be an engineer.)
4. No new transporter.
5. Gnomish Lightning Generator has a cast time, and doesn't do enough damage to ever be worth using.
6. Grenades have the same problem, not having a strong enough effect to be worth the time investment to use them.
Engineering isn't totally worthless apart from that. I'm using the massive Stamina trinket when I feral tank, and I love the mobile mailbox and vendor. I got a fair chunk of use out of the parachute-cloak enchant. I also totally overlooked the self-enchant that gives you a "Use: +haste" ability on your gloves, which might be the strongest reason to be an engineer.
The main problem is other tradeskills just seem to have more. Leatherworking has about 2 solid epics per druid spec in addition to some great self-enchants to bracers and legs. I can't wait to level my shaman with leatherworking after my sad times with the druid engineer.
