Greetings fellow Ice/Ice/Ice tanker. I am suprised that after looking through all excellent builds you have presented here that I did not see one that included the Leadership pool. I am sorta suprised, Leadership is very natural for ice/ice/ice I think and also beneficial. I took it instead of taking any of the attacks from /ice except for ice patch, freezing touch and taunt. Maneuvers tactics and vengeance, you get a boost to your defense which is quite helpful as well as helping others. Tactics doesn't help me much, but it does give me +perception making me the ultimate stalker spotting machine-never had a problem seeing somebody that's invisible, ever. And vengeance, I 4 slotted it with defense. The first person to die is the last person to die for a while, and there's no way in hell you're going to go down while vengeance is up.
Just my opinions and justifications, ice on.
