path points

ok, being i never lvled past 45 legit, i dont have a good idea of how the path points work, do i get more points for using my dk in harder quest/raids? is there any proven way to get points faster is my main question.

You basically get 100 points every time you trans and if you do enough damage.

I sometimes do a trans run to Hidden because you give enough damage to him to acquire the 100 points you need.

And I don't think there's a method that makes your transformation lvl faster, have to do it legitly x.x

but is there better quest to use your dk or pali on to get the most out of it?
