You pull you tank question.

You only used half a full sentence, so I'm going to spell this out instead of taking the response in the worst interpretation that I could.

Support member =/ Support Role

Role = reference to the kit of abilities available to a player. A Damage Role is a kit of abilities primary focused on dealing damage. A Support Role is a kit of abilities primary focused on helping others.

Member = The player themselves, which means any adjective is a reference to the primary objective/purpose of said player at a given time. A supporting player/member of a party is any person that is helping another person. They are not the initating instance of a mission/objective. If a Tank Role starts to attack an enemy first, any secondary person that is aiding that, is supporting them, regardless of the Role. An example would be you, as the WoL, summoning the Scions. They are healers, dps, and tank roles, but all are considering supporting you in a fight because you were the one who initiated it. This usage of support is relevant to perspective. Another example:

Add 1 is being attacked by the Tank.
Add 2 is attacking a Healer Role.
Healer Role begins to attack Add 2.
A Damage Role begins to attack Add 2. <- Damage Role is a supporting member to the Healer Role. Healer Role initiated attacking Add 2.
Add 3 spawns and begins to attack Damage Role.
Healer starts to heal the Damage Role. <- Healer Role is a supporting member to the Damage Role. Damage Role initiated (via aggro range) a confrontation with Add 3.

You can have two players with different Roles considered a support member at the same time.

From a Tank PoV, because they initiate 95-100% of the engagements inside of a given content, they will refer to Damage Roles and Healer Roles as supporting members in general because the default plan is not for them to making their own objectives throughout the instance repeatedly. Supporting the Tank Role is their primary objective, and supporting the other roles as situations come up are secondary objectives.

Okay, just going to ignore you after this, but in FF14 terms tanks and healers are the support roles. Not the DPS. Putting you on ignore now.
