This is an excellent example of how the MMO genre can evolve in new and exciting ways. Take some old concepts and change them to make them new and exciting.
Everyone is so afraid to break the MMO "mold" that EQ, Lineage and WoW created all those years ago that the entire genre has become stagnant. Action MMO's became a "thing", but that was just the mixing of genres and not a true MMO evolution. Part of what makes an MMO and MMO is thoughtful, strategic combat...not flashy sword dancing.
The addition of armor and energy types to add an additional level of strategy to combat is an amazing idea and deserves consideration as an addition to any MMO.
Thank you for sharing this!
