Personally I happy with a passive damage increase as I enjoy our rotation and playstyle right now. The one thing I want to see and believe should be done is elemental blast made baseline and replaced by a new talent at 90. Blast imo fits the ele rotation, it feels right.
The only other suggestion I would have (and mentioned in another thread) would be for earthquake to work in someway with our fulmination, maybe something like as we gain stacks it lowers the cast time of earthquake (not sure on this one), or increases its damage. That imo would be a new way of bringing EQ into our aoe rotation, especially with the new chain lightening changes.
I dont think an 'execute' talent would work, I don't feel we need it and I also dont think it would feel right.
