I'd just like to suggest a couple changes to Brit Air to make losing to it feel slightly more fair. Please note I'm not suggesting every nerf should take place together as you'd risk overnerfing, but instead just offering some potential points to touch up on.
Empire Strikes - while undoubtedly an incredibly powerful AoE tool, it doubles as a potential burn spell to find lethal from hand, my suggestion is it only hitting units and no longer burning enemy HQ as well as it simply does too much atm imo.
Close Air Support - Adjusting close Air support is a frequent suggestion and I'm not fully convinced it's the right focus point got nerfing Brit Air. One of the main nerfs I see suggested is to make it 2k, instead I offer an alternative which is for the card to only buff attack damage and not add any defence values, this way Brit air can still be a very aggressive deck with out the 4 or 5 hp early game bombers we've come to expect. I imagine this suggestion will be less popular how ever I feel it more important to add extra perspectives and ideas instead of copying previously suggested nerfs.
