If Glyph of Energy is casted, AI will prioritize skills costing 25 energy. (Or more, not that there is any of those)
If Glyph of Lesser Energy is casted, and it reduces energy cost by 10 points. It will prioritize skills costing 10 energy or more. If it reduces by 11 points, it will prioritize skills costing 11 (15 in practice) or more. So when using both Glyphs at 13 Energy Storage, heroes will prioritize 25 energy cost spells. ANd given that Rodgort's is the only one on your bar with that property, you can catch my drift? ;P
Simple solution, use Elemental Attunement instead of Glyph of Energy. It adds damage through higher attributes, spams skills of all energy costs and the hero doesn't need to waste time casting glyphs in the first place.
Fireball, Rodgort's, Liquid Flame, Glowing Gaze, Glyph of Immolation, Fire Attunement, Elemental Attunement, Aura of Restoration.
Of course, there is a hundred variants to this build including those who bring "Fall Back" and "Stand Your Ground".
