So the war corporation's shields require 8x energy to absorb same direct-fire damage as venture and 2x gso? I knew there's fishy wonky stuff going on, but didnt imagine to such magnitude.
So you really think they should be bigger
and more efficient...? Best in all ways, because: Hawkeye. Hmm.

So HE repair bubbles should also be fastest and most efficient (and big)?
With the HE shield bubbles being twice the radius of Venture's, that's 8 times the volume, inside. So you're able to scale up the battery capacity way more rapidly, too. That's a pretty powerful implicit feature...
inflating or scaling down the blocks based on their "popularity" from usage statistics
Kae greatly reducing the cost of the Venture bubble makes a lot of sense. It's very weird (and off-putting) for players to see that it cost more than the HE shield, with no justifying explanation (when obviously a tiny bubble). And reducing that price it makes sense to nerf the damage drain rate too, of course. (But it definitely shouldn't be worst than HE's, in this regard.)
My guess would be folks tried it, got blown up by <insert explosives of choice here> with battery power left, dropped it and never looked back.
Doubt many would go that far. More likey most try it on a tech, see the bubble is tiny, immediately remove and never look at them again. High price might not even be considered half the time, either.
We kinda' forgot the issue of the GSO repair bubble. The thing is more expensive, than the shield now! That... that's just wrong. Please, reduce it's cost to about 3000 BBs!
6000BB does seem like a heck of a lot for such an early game block (literally getting one in the first 5 minutes). That's not going to be even vaguely affordable to buy early on... I guess you just have to kill enemies for them? I don't know the early game well enough to know what GSO level you start seeing many enemies with bubbles... So if you loose the free early on, that's going to be kinda irreplaceble.
I'd have guess you devs worked through this kind of fundamental already, though,
@kae?
