It states that you gain “+6% cast speed” and “12% more damage per extra projectile” but in fact you gain only “15% more damage per extra projectile”, if my calculations are correct.
No offense, but don’t you think there would be fewer issues like that if data displayed in UI relied on actual data used in code? I understand that it’s not that easy and maybe there will be some internal changes in future that will help to get rid of such issues. Perhaps it would help to have some kind of validator to check that skill tree mutator complies to skill trees UI data.
