Mk 47 is an AGL who specializes in breaking HP Shields. Being an AGL already puts her pretty low on the priority list as AGLs inherently don't have a clearly defined role. ATWs break Force Shields and MTRs kill large groups of enemies, while AGLs fall behind these two in practically all situations. If you need to break Force Shields you're likely to want to field all three ATWs before you want to tag in an AGL (with AGS having some minor considerations due to 3 Range and Pierce focus), while against no or minimal Force Shields you'd just field MTRs before considering AGLs.
All in all this makes her pretty niche, though occasionally useful if you are fighting enemies with HP Shields that are linked and either have already deployed all your ATWs or do not need them, or similarly with your MTRs.

Launch 3 grenades to deal 0.33x Lethality and Pierce per grenade to enemies within a radius of 1.5.
After damaging a target, subsequent damage is reduced by 35% for 5 seconds, does not stack.
Level 10 Effect Fire 3 airbursting grenades that deals a total of 15 instances of 0.1x link-scaling Damage within three random areas, dealing half damage to Armored units.
Level 10 Effect Reduces the Damage penalty of regular attacks. When making regular attacks, each instance of Damage on the same target after the first has its Damage penalty reduced to 20%.
Level 10 Effect Each grenade fired by regular attacks deals an additional 100% of self Pierce as Damage to HP Shields to enemy units within the grenades' area of effect. This additional Damage is only effective against enemies with HP Shields.
Mk 47 technically has her own unique mechanic similar to AGS. It's just that this unique mechanic is that she deals less Damage to a target after hitting it for 5 seconds, and wastes her entire Skill 2 diminishing this drawback.
Mk 47 is an AGL with basic AGL targeting, prioritizing Force Shielded enemies but otherwise completely random.
Her entire niche is centered around converting her Pierce to HP Shield Damage, which is not that useful but if you have nothing else is better than nothing.
All this combined makes her one of the less useful HOCs, together with QLZ-04.
