many of your questions are already answered in the above thread, try a little detective work next time.
1. Getting a skill tree just for a passive is a waste IMO. Most passives don't pay off big until you max them at 60. Heuksal goes from like 500 to 1k extra hp. Ice, Light and Pacheon all have a significant increase from 50 to 60.
2. I don't have white hawk. See #1 for my explanation.
3. Well, you can keep a mastery gap and level that way. It's slow but not too slow. Or you can farm your brains out at 16. Up to you.
4. Mastery is capped at 300. It's not even possible to get every passive maxed. At most you can max 5, but then you're stuck at level 70 with 5 level 60 masteries. 4 is as high as I'd recommend.
5. Looks decent. Just try things out for yourself and see how you like it.
7. Your choice. I use both ascension and heaven chain in PVE even though I don't use them in PVP. They give good damage for low mp. Most monsters my level only need two chains to die (maybe one other hit, but normally not).
