For example:
Make HQ Require 100K lbs of damage within a one hour window. Completely flattening opponents HQ wins reset.
Result:
- Opportunity for meaningfull deep heavy bombing missions
- Meaningfull bomber intercept role and need for high air patrol
- Escorted bombers, knowing that intercepts will be coming
- High altitude air combat ala ETO over germany
- Strategic element to base capture (take bases that provide path to HQ or make defence of HQ difficult).
- Quicker map rotations (think about it pizza haters, one coordinated 2am HQ raid acheives reset).
The only impact on furballers is that the map changes frequently. The only impact on land-grabbers is the added element that *which* fields you capture (or defend) in what order may matter more.
Just one idea, I'm sure there are others.
