Where are class trainers in Outland?

From wow.incgamers.com

There are no class trainers in Outland. You have to go back to Kalimdor or Azeroth to your favourite trainer. All trainers are also in Exodar or Silvermoon.

How to best handle this? Get in Shattrath City (Terokkar Forest), set your Home in there and use free portals to all Old World cities.
