As a level 80 Warrior, this statement is true for about the first 60 levels. After that things do get a lot harder and dont seem as easy as when you first started out. Also trying to find the right traits for a balance.
To many traits towards one or two lines and you become a glass canon. Going the other route and it takes forever to kill something. Heck…having 31k HP isn’t so bad….I just let the DPS people go to town when I’m taking the damage while in a group.
