Ok first off the easy answer:
Crippling Strike: (we all will agree on this) at least all the ones that were here for the creation of the warrior thread. This attack is by-far the strongest attack you will have. If you are going to hash it out, this one is the skill for you. 10 of 10 points.
From what i can see from the skills you have, you usually bet on killing and hurting many enemies at once while you take less damage (blood rage speed and slam)
so...
Skip leadership, you only really need it before you hit level 60 (if you think you need it anyway) I'd get yourself a better skill that would benefit your team more.
Since you are more a DPS (damage per second for those who dont know) get crippling strike and warcry. The add to damage to single enemies are what you will need against the last bosses. (since their attack is much higher)
138 for strength or 136 I forget the stats for the Immortal weapons but you can invest in what you desire. If you believe in your pot use or a healer then place in energy for more mp use. Otherwise id hit endurance for hp and def.
