Lvl 70-80
You now have to have complete and total patience. Get a party to Forgotten Pathway and lvl all day long. Skill points should be obvious now, since you only canp ut one more into Crushing fall, the rest will go into Haste. Skills look like below.

Ranged Mastery- 10/maxed
Haste- 10
Aura- 20/maxed
Bind- 1
Deadly Assault- 20/maxed
Burst- 1
Wail of Valkyrie- 1
Crushing Fall- 10/maxed
Shadow- 1 (Optional/if not put point into Haste)

Lvl 80-90 The possibilities are now endless. Do what you want and stick with it. I will show you how you should look at lvl 90. I suggest getting a Skill Intial and getting rid of Shadow, Wail of Valkyrie, and Burst.

Ranged Mastery- 10/maxed
Haste- 20/maxed
Aura- 20/maxed
Bind- 1
Deadly Assault- 20/maxed
Crushing Fall- 10/maxed

You have 8 points left over now.
