Another interesting thought to DoTs providing lunar/solar energy would be what about items that have a DoT component (ie 4pcT10). If we take Languish for example, if it could provide energy what type would it give? Would it correspond to the spell that charged the “Languish bank” or fall more in line with the energy provided by Starsurge. I’m not sure of an easy and clear way for Blizzard to balance energy granted from a DoT that comes from a set bonus/item, so I think we may find that energy from DoTs only comes from our class spells (MF/IS) if they allow that at all.

However allowing our DoTs to contribute to energy generation leads to some very interesting options for Blizzard. For example a new tier bonus could be that on top of the initial energy gained from the application of the DoT, there is a chance that you could gain energy (albeit a small amount) from the periodic damage from the DoT (ie, 5 lunar energy from the initial cast of MF, and the potential to gain an additional 1 energy per periodic tick of the DoT for a possible maximum of 10 energy per MF application). I would find this to be a very attractive set bonus

As for DoTs giving us Lunar/Solar energy; I hadn’t thought of that but I get the feeling that Blizzard is not going to go in that direction. This idea hinges heavily on the ideas that a) our DoTs contribute to our Lunar/Solar energy, and b) that each individual DoT on each individual NPC contributes to our energy. If I were to DoT up a group of mobs and each individual DoT contributed to my energy, it may be possible to avoid having to cast Wrath/Starfire/Starsurge to ramp up my energy and I could just swing from Eclipse proc to Eclipse proc like we do today. I think it’s far more likely that our rotation will be like your simple rotation example above.
