Say the Security has a health command post. A Security engineer upgrades this command post so it gives 2 additional health pips instead of just one. Then a Resistance operative comes along and hacks this command post. Would the Resistance get the 2 additional health pips, or would it be reset and a Resistance engineer would have to come along to get the 2 health pip bonus?
I'm thinking it'll be reset whenever its hacked, but I I'd like it more if the upgrades carried over from side to side. Make command posts a more valuable asset to defend, as your team would lose two health pips while the other gains two, as well as a more attractive to attackers.
