Did they fix support participation?
If I remember correctly they did make some changes, but I don’t remember exactly what, let me see if I can find a patchnote on it or something.
EDIT: Found it.

General
Supporting your allies will now contribute toward earning rewards for killing enemies and damaging event bosses. The actions listed below now cause a percentage of the target ally’s damage dealt for the next several seconds to also count toward your participation. In addition to that, damaging an enemy’s defiance bar will also grant you some participation toward receiving rewards from that enemy. In order to discourage AFKing with boon-applying auras, you must still be actively attacking targets to receive rewards from them.
Applying boons to an ally (small percentage).
Removing conditions from an ally (small percentage).
Reviving an ally (large percentage).
Healing an ally (percentage scales based on how much healing is given).
