I think it all aoe support fields could use a visual addition that reflects the benefit given by the field as well as the field type (pref as large icons that hover over the field). This would help player interact better with other classes’ skills w/o having to simply know another classes skills
Ex: if a green plus and a light element icon hovered over well of blood, every player would instantly know they could gain hp from it and that it is a light combo field. Well of suffering could just have a dark element icon so that players know it is a dark field, but wont gain from standing in it.
