POV From a non-Pocket Healer | ꒰ა Mercy Main ໒꒱
I had played Mercy for over 30-some odd hours and the most cringe fest Mercys in existence are Pocket Healers.
What are Pocket Healers? Is when a Mercy assign themselves to literally one character. It could be their best friend or could be the Tank of the party.
There are a lot of downfalls to a Pocket Healing Mercy, as for the first thing, Mercy is designed to be a Group Healer and is most effective when the Group is together.
Also assigning yourself to one person such as the Tank is a L Move, as the Tank has Shields and other means (such as self-healing) that they can take care of themselves while the Mercy gets the DPS / Others caught back up.
DO Not Pocket Heal, Pocket Healers are why Pros cringe when a team mate picks a Mercy during Comp. Have the group stay relatively near by, and heal like the way Mercy is designed to be.
