Please rework the elementals so that:
What would be even cooler (but also way more intense) is if the elementals would not despawn after xx sec and just stay there. The glyph would start it's CD the moment the cast has finished. The elemental special skills are on a seperate place (maybe like hunter? I don't really know how it works there). Changing elementals works as soon as the glyph is off cd, casting a new elemental kills the old one.
Viable != Optimal
Not viable = You only get carried, 10 players with a build as "viable as yours" can't properly do it.
