freeze pulse + iron will mara

For whatever new hardcore league comes out I think I want to do a Freeze Pulse Marauder using iron will.

This is what I have so far as a possible build. Any optimizations or further suggested progression?

Would the marauder be the best start point for life based fp iron will? Any help or feedback is appreciated it. Thanks

Um, I would point out that the Iron Grip passive (selected in your passive tree) wouldn't help your freeze pulse. Freeze pulse is a projectile, but isn't an attack, so Iron Grip wouldn't apply to it.

Further suggested progression. Head on up to Whispers of Doom (through Hexmaster), grabbing the Freeze Duration and Breath of Rime passives on the way. Also, cast speed would probably be helpful, so grabbing Prestidigtation and the Cast Speed nodes between the Templar and Witch zones would be your closest options. Combined with a faster casting gem, you should have a decent cast speed.

oh wow i didnt know that. okay thanks!
