I don’t want to throw figures at you, but I hope that my opinion is still understandable.
I think the change on Earth Magic XI is senseless. With the last balance change you’ve brought that Trait into the game. If you play the elementalist with condition damage, this Trait was a very useful option. It transformed 10% of toughness into condition damage. This way, it increased condition damage to a nice value.
I don’t understand why you now want to change this Trait. The idea of the new Trait is per se really good, because it expands the defensive abilties of the elementalist. It sounds very interesting. However, I would miss the possibility to gain some condition damage out of the defensive attribute toughness.
Please rethink the change again. Otherwise, the elementalist loses a lot of potential, regarding condition damage. I fear that condition damage will turn out to become useless.
