Not sure if this has already been reported, but I haven’t found anything recent in the matter (apologies, poor Google-fu). Anyways, it seems this delicious slice of mature Stilton is still unresolved.
Playing some customs last night on Distillery and Orbital Drill we’ve found you can still heal through domes with splash from Caira’s grenades and Lazarus’ healing burst. Did not test any other medics or support’s shield burst, but I would also expect them to go through.
Should probably be another topic, but on a different note: Tech Hank’s pre-applied shield still reveals Laz if he cloaks.
