it does help either with the leveling up bonus and gives you an all around faster regular skill advancing rate. However it does not affect their respective leveling tree. Only your characters normal abilities (i.e. alchemy, smithing, restoration, light armor, one handed, smithing all level at the 15% rate)
Oh he meant for the Vamp or Wolf perk tree? Then as 216 said no. There are a couple of tricks to speed it up for the Werewolf though copy/paste from the Lycanthropy wiki page -
THERE IS A WOLF PERK TREE?
Dawnguards adds one just like the Vampire Lord tree, does give the Werewolf an much needed power boost and has all the powers from the totems quest looks awsome too.
WOW I DIDNT KNOW THAT DAWNGUARD GAVE A WEREWOLF PERK TREE!!!!!!!!!!!
HOW DO I GET IT?????
just become a werewolf, then press the menu button while in wolf form and it'll pull up the talent tree.
Yeah, the Werewolf perk tree pretty much turns the Werewolf into an extremely viable option for combat. Still no health regeneration, but it does add a perk to recover more health when feeding on corpses.
There's the Ring of the Hunt for that though, but that only works for your Beast Form Transformation, not a Ring of Hircine transformation.
