Just awakened my Feoh, I didn't bother keeping any of my old skills (emp echo/aracane), Are they that much better than my new acquired skills and would it be worth re rolling just for those skills
Rerolling for those 2 skills is not a good idea. Soon those 2 skills will be removed anyway and also on later levels the new skills are better.
Oh btw they have changed the system so you could not use emp echo with wiz harmony.
