Event tagging as an FB Healer

When doing OW dailies to ("Complete 4 events in xxxxx zone"), it sometime seems like bad etiquette to F1 AOE everything when there are lots of players trying to tag mobs during the same event. I've found it is relaxing to just use F2 and/or F3 skills (with Legendary Lore trait) as a means to get credit in events without being a "kill-stealer".

I may not get as much random mob loot, but often those events are in low-level zones anyway.

Anyone else do this for OW events?
