Exp gain question

[JunseiKei]

This also begs the question of if you, the healer, are also dpsing mobs during healing downtime. If you don't at least tag a mob (even in a dungeon) as a healer, do you get exp for the kill? I don't heal, but that might be something you should check on to make sure you're not missing out.

In dungeons, you don't need to DPS at all to gain EXP. If you're partied, the party needs to tag to gain credit (like quests). It's only special open world mobs, like hunts and FATEs, where tagging is highly suggested as a healer. You can gain credit from just healing, but tagging completely ensures it (as members that become greyed out or untarget-able don't contribute toward the healer's credit if they only heal).
