GAC Defense Attrition similar to Conquest

I feel this entirely defeats the purpose of GAC. Sometimes you can't beat an opponent's team. This would erase all strategy of what teams to use on attack and also makes setting defense feel pointless. There are already many teams that feel obsolete in GAC; this would give them a use, but a use as fodder just to wear down that one tough team. You say there can be a relic delta and undersize restriction (which just sounds overly complicated to implement) to prevent cheesing, but we already have so many useless units at pointless relics due to requirements. That wouldn't really solve anything. I would not welcome the complete rescaling of banners necessary for this. I like how it is now with no further penalities after the second loss.

I get that some datacron sets are extremely frustrating and broken. But they've all had counters. If you can't have the presence of mind to plan around certain counters, then you'll use. Implementing this suggestion will completely devalue people's investments while simultaneously taking away the only edge a roster disadvantaged f2p might have.
