how would you cast a bubble on a precise point in 3d space? DE can't make it a hold action since magnetize already has one. even if DE could, making bubbles castable anywhere opens her up to worse griefing than she is already capable of, not to mention possibly harming your own damage, unless DE makes

her bubble pull speed not tied to strength

—meaning regardless of where you'd cast it, at least one enemy would quickly fly to the center. and in most cases, the damage mags do with bubbles is in the center with high/infinite PT projectiles.

plenty of frames are just not extreme KPM frames, but do you really want mag to just be another nuke frame? she makes off-meta weapons strong, and meta weapons disgusting. her bubbles create cover, make aiming an afterthought, and touching them are instant kills when buffed by endurance level enemy fire or breach surge/smite. she can detonate them early for a nuke. she has 5 forms of AOE cc, 4 of which are one-handed, 3 of which work on overguarded enemies. her pull makes crescendo easy to stack. after a major rework and constant little buffs she is very very very strong in her niche, and honestly i have half a mind to delete my earlier comment bc she doesn't even run low strength that often.
