I always thought the Seer multiclass had lots of potential. My only concern is that it's really hard to make a balanced point progression (if you want to use your ghost pet) because of the amount of skill points you need to properly build a ranger... But I think it can be done very well, and wreak havoc in PotD.
Now, Ghost Heart is the obvious subclass in Ranger, but what is the best config for Cipher? No subclass, Beguiler or Ascended? Beguiler COULD be perfect if the bonus was on shred spells instead of mind confusion (forgot the proper keyword name)... But it's very easy to proc flanked between the debuffs and the pet. Ascended can be great, but the point of the class is weapon damage, so I think no subclass would be the most well-rounded option indeed.
Now as for the weapon, I understand it should be using either hunting bows or longbows, right? That makes the damage bonus from two-handed style get added to the soul whip bonus, which together with all the accuracy available should be amazing.
Why is Biting Whip bad without the community mod? I understand it raises damage bonus from 20% to 30%, isn't it so? This makes the point expenditure more "expensive" than 2-handed style, but 10% more damage doesn't sound bad. Is Draining Whip always better? What does the community mod do?
Skill wise, because you have the shred DoTs from the cipher side, then you don't really need the PL1 shot skill from ranger, right? Then focus on getting DoTs, debuffs/buffs, Accuracy, Penetration and Damage (for you and the pet) and it should work pretty well.
