defense of troll warriorFollow

ive decided that when i have the game up and running tomorrow (when i get my new video card) that i shall be making a troll warrior. seeing as that warrior is not going to be the big damage dealer compared to the other classes and that he will be taking massive damage as the main tank in the group ive decided to go with an approach of defense and shall be using a shield and something else. what skills should i be investing in? any advice for me on this matter? ive had experience as a main tank with my old troll shadowknight on everquest so know mainly what to expect as a tank. just looking for skill advice. thanks all.
