I agree with everything said before. I would also add in some Curses, particularly [mwcard=MW1E27]Marked for Death[/mwcard] . Agony could also be useful. Besides Curses, you might consider Block to help protect your critters, and Regrowth to heal yourself.
To add to the Equipment, you should put on a Veterans belt. Between the 3 armor from boots and chest piece, and the 3 armor from Fortified position and Standard bearer, you should be pretty beefy.
You might include another Shift Enchantment or two to make sure Fortified Position stays where the action is, but it might be a better idea to include walls and pushes (as previously mentioned) to keep the action where Fortified Position is, lol.
