You guys are overrating human racial in this bracket. The human racial only helps with stuns, and resets a GCD of 30 seconds on your trinket.
The gnome racial gets you out of snares which are far more prevalent, only has 1 minute CD, doesn't trigger a trinket GCD (meaning you can use them back to back), gnomes get a slight additional Mana or energy pool, and gnomish engineering bonus allows you to wear ilvl48 trinkets instead of the ilvl42 for those who don't have AGM or fishing angler.
And they can hide in bushes.
