When I play my mesmer, what I feel I lack is more information about my current created illusions : mainly their hp and their type. So I would like to suggest that the 3 dots representing our current illusions be modified to represent their hp and type. For the hp, those dots could be small hp pools with only 4 states (100%hp, 75%, 50% and 25%), and for the type of illusions, they could have different colors or different forms : blue dots, red triangles, yellow squares etc.. And also, It would be great if we could have an indicator that shows us when is the illusion going to attack, maybe that dot starts to flash, or the outer boundaries of that dot starts to replenish(like boons and alterations).
What do you think ?
