The ranger actually can DPS
I used to have it as 10/15/0/20/15 but I found the 15 points in Beastmastery didn’t make any real difference at all, and I was losing a lot of damage overall. 30 in Nature Magic lets you take either Spirits Unbound or Strength of Spirit; the former is quite useful in “AOE dodging” fights like Volcano Fractal or Molten Facility, because it keeps the spirit out of AOE circles, and also sometimes help it avoid big one-shot attacks because it follows you pretty closely. I found I was able to use it to keep the spirit alive against stuff like Effigy pretty well. The latter is , well, straight damage. It’s good, plus Bountiful Hunting is another free 5% damage for only 5 more points invested.
With Vigorous Spirits and Spirits Unbound and the new spirit health buffs, it actually takes quite a bit of sustained beating to take out the spirit.
