TF2 and Siege, no?
The spy and the sniper are the go-to classes for the general casual tf2 community, and are considered supports in that game.
In siege the most picked attacker atm is Finka (who is the healer on the attacker team), and on defence it’s mostly the people with the best supportive gadgets being picked (Jager, Melusi, Thunderbird, Kaid, Mute, Valkyrie) rather than the all out dps flankers (like Ela, Vigil, Caveira).
