I found an old suggestion in for 0.7 version about something alike but I think I can still suggest it.
Every completely destroyed Firebases should cost tickets.
I am not sure how many but maybe 2-5. At least two - a truck costs 2 and I think a FB is at least as worth as a truck...
Since vehicles cost tickets I dont see a reason which speaks against my suggestion.
Losing a Firebase in RL would probably affect the army in a big way. Though I am not completly sure what FB is exactly in RL and how big it usually is but I guess with a radio and HMGs and razor wire it costs a bit in RL.
So why should it be for free in PR?
I suggest team loses 2-5 tickets for a FB that is completly destroyed by the enemy.
And by completly I mean it can not be rebuild but a new one has to be build.

Hunter
