I am pleased to see this development finally coming to fruition.
I have been anticipating this for quite some time.
Though, now that it is here, I have some concerns regarding the relatively low costs associated with the shield upgrade and its corresponding shield hit points.
Would it not be more logical for the shield to be far greater in durability and incur a slightly higher resource cost?
After a brief overview, I must admit that I find myself favoring Spikey's original implementation of the upgrade changes.
That change aligned more closely with an advanced upgrade suitable for late-stage front-line use, as opposed to mid-stage use.
I hope this change has not been firmly set.
Then if so, more tweaking could be done before it goes live.
If I may suggest, this could be mitigated by introducing another upgrade option for the bubble shield.
This additional upgrade could be designed to align more with a mid or late T3-stage, as well.
This would also keep the Bubble Shield useful as it currently is in live games - Shielding a valuable building and whatnot.
Nonetheless, I extend my gratitude for the remarkable efforts put forth by the FAF team.
I can't wait to see it when it goes live!
