For starting stats on a Warrior the two choices are generally Stamina or Charisma.
If you think you will ever change your mind about raiding, dump into Charisma for the extra chance of

If you know for absolute certainty that you will never raid, then dumping into Stamina is fine. It will allow you to have more HP in more situations, depending on what buffs your current group has access to, as well as what gear you have access to.
Do not bother dumping into Dexterity or Strength. They are very easy to cap with buffs. As an example, with

Trolls also have a decent starting Dexterity, higher than Ogres and Barbarians. Strength is fairly easy to get on gear as well. Dexterity is a bit harder to find on gear, but there are enough options for you to make up any Dexterity you think you may be lacking.
Stamina has less buffs available for it, you mostly will just have
