Going to attack it at a different angle.
I think instead of fuel or radar, why not CV downtimes?
If the HQ is down, any CV destroyed in the next 30-45 minutes (even if the HQ is restored to full glory 15 mins after the attack, realistically, there would still be a delay in transmission because they would need to find or repair communication equipment), has their downtime increased by 15-30 minutes. So instead of 10 minutes after being destroyed it would be 25-50.
I think we need something else in addition to my above suggestion, for maps without CVs. However, I am trying to think of ideas that don't punish players who weren't online during the attack.
I mean, what would you do if your side was limited to 25% fuel across the board for the next 30mins to 90 mins? WIth that being increased by strats to who knows how much (lusche)?
Does anyone have a practical idea, perhaps something abstract, that makes it so players joining in don't get punished, and it doesn't completely cripple one sides offense/defense?
Sure, the attacking side needs an edge because they attacked a critical component of the enemy. But I think it would be wise to think 'outside the box', perhaps only being able to take off from certain airfields? Or certain ENY planes can't be used (like perked - 5 eny planes for X time). etc.
Just random stuff.
Any ideas?
