When I was playing with Anjali, I stacked EVERYTHING I could into Will. I've not attempted Hard mode yet but I have Crit near 6000 damage with Fall From the Heavens maxed out in Heaven's Fury (Inflicts an additional 10% per rank) and about the same DPS from Volatile Barrier with Fiery Blacklash maxed.
The skills that I found to be very heavy DPS with Anjali are:
- Hurl Spear
- Fall From the Heavens
- Volatile Barrier
I would mostly put everything in Will except the Human Weapon, which I would invest into Agility. Use her Archon stance to build focus for those two skills and you should be right. The high Will makes all her skills fairly strong but not the standard attack skill, you need it to be weak to build the Focus for the hemorrhaging skill DPS. That's just me though.
