I am also having mixed feelings about the change for the Bubble Shield, though I didn't want to be the first to say something without having tested them in-game.
However, now that others have spoken, here are my two cents:
Resource costs and regen time are a huge buff, yes, but the lack of shield HP is what was the main issue to begin with.
As far as I can tell, almost no one had any issue with resource costs or regen time, but rather with the SHP and SHP-related ratios with the associated resource costs.
To put it bluntly, what's the point of the upgrade if the Shield will collapse sooner due to a lack of HP during a push?
Sure it'll regenerate sooner, but, by then, 60 seconds of time without a shield, that's detrimental.
(Just ask the Cybrans).
If 2 or 3 Parashields can obtain the same protection for FAR cheaper, then I'll gladly take the Personal Shield over the suggested changes, regardless.
"Oh, but Overcharge Protection"
Yes, that's still one benefit of the Personal Shield, but that tradeoff is still not worth 2,000 HP.
I'd also argue that even if a mobile shield dies to OC, it paid for itself because it still protected the units anyway.
I quote myself from this Github Post:
(The balance changes suggested for the upgrade have been updated since this github post, but the information I mention is what I am referencing.)
The Bubble Shield's SHP-to-Mass ratio is still absurdly low when you compare it to the Personal Shield's ratio.
Bubble Shield (Current): 9,000 HP for 2,300 (3.913)
Bubble Shield (Suggested): 9,000 HP for 2,100 (4.285)
Personal Shield: 19,000 HP for 2,300 (8.261)
Even with the very slight decrease in mass and build time, the tradeoff between Bubble and Personal Shield is still far too great.
Personal Shield will still take precedence over Bubble Shield.
For 200 mass, you more than double the HP of your Shield.
No one would pass that up. Saving 200 mass is not worth losing out on 10,000 HP.
If I may offer, a more realistic approach would be to have Bubble Shield at around 12,000 SHP for a Mass cost of 1,500.
This would grant it a SHP-to-Mass ratio of 8.0. (Energy and BT costs can be adjusted to match.)
Slightly worse than the Personal Shield's ratio and stats (7,000 less HP), but still enough to make it a lucrative upgrade when compared to the Personal Shield.
That said, Bubble Shield and Personal Shield are not the same upgrades and should not be treated as such.
One is meant to protect one unit, while the other is meant to protect multiple units.
But, at a current HP of 9,000, it doesn't do much other than offer a few extra seconds of protection.
Regardless, I am happy the upgrade is still a focus to better adjust.
As for the Stinger... nothing on the Preloaded LAB idea from the Discord Server?
