Fixing the engineer

If Anet actually wanted to fix engineer, here's what they would've done:

1. Increase attack speed of pistol #1 (fragmentation shot) by 50%
   
   
2. Reduce shield #4 (magnetic shield) recharge to 20s
   
   
3. Add 1s stun to pistol #3 (static shot)
   
   
4. Increase radius of all bombs in bomb kit by 60 units
   
   
5. Increase all condition duration by 20% in the trait expert examination
   
   
6. Increase rifle range to 1200 units
   
   
7. Decrease gyro leash length to 180 units, teleport gyro adjacent to engineer when outside of leash length
   
   
8. Return gyro to instant cast
   
   
9. Increase shredder gyro speed by 33%
   
   
10. Gyros blast when destroyed (a la turrets)
    
    
11. Re-enable throwable turrets
    
    
12. Make turrets immune to conditions
    
    
13. Reduce gadget recharge by 33%
    
    
14. Remove RNG from thrown elixirs
    
    
15. Change A.E.D. to instant cast
    
    
16. Increase damage bonus from glass cannon to 20%
    
    
17. Remove cooldown from Thermobaric Detonation
    
    
18. Reduce cooldown for Incendiary Powder to 5s

...and many more, but that would be a good start to bringing up Engineer to baseline level with other professions.
