I couldn't find the info with Google and since I don't have premium account I can't use the search feature.
There seems to be inconsistent information about switching between goblin and gnome engineering. One source said just go to a place by Steamwheedle in Tanaris and read a book, another say to drop engineering and relevel then choose other when I get to 200. Yet another source says you can't change even if you dropped engineering.
What is the current method that works for switching or am I stuck as gnome? I'm tauren druid and my main spec is resto (about 90% of the time) but I have full tank gear and can do around 2kdps as cat or tank with 30k armor and 24k hp, 522 defense. Goblin engineering would have done better for dps. I liked gnome though for the toys.
