Players should have elemental shields just like enemies do. Right now it feels as if all players have white shields only. I think players should be able to equip themselves with elemental shields. They could either choose it based on their gear or have it based on their equipped class. Programming this feature should be relatively simple given that all enemy and player attacks already have elemental properties. Give players elemental shields and make these properties affect them too. The graphical part requires a bit more work since new UI elements and visuals for the shields need to be created. Good luck! I'm sure this will be a great feature.
