Initially I would my points for Rohane into Critical Attacks and Damage Increase. Stunning is good later on in the game, as are the two Innates.
When you get Mipsy, I advise Direct Damage and the two Innates. I also put some into Group Haste. Damage Shields and Slowing I tend to put my excess points in.
With Talinia, I put Increase Bow Damage and Multiple Targets up to 11. I also use Shockwave and Innate Haste, and the final points are spread through Slowing Strike and the other Innate.
Velm - Group Healing. To 15. There's no option about this one ;P The two Innates are important, though I get the Haste up first as it means Velm can heal quicker. I'm also putting points into Group Shielding, and probably Mesmerization.
I also never put any of my points higher than 11 (with the exception of Mipsy's DD and Velm's Healing) until I have my final armour, as it usually comes with +4 bonuses.
Of course, these are just the ones that I use, but I've found they work quite well.
