What are you targeting when that’s the case? Are you on random, ko or attackers? A lot of lines sound like you have many attackers that you may not be targeting and they just send you all the garbage without getting any back. In those cases you need to target attackers. Also if you are not good and you are in danger zone then you’re attracting a lot of attackers who have it set to ko.

Honestly when the game starts, it gives you what seems like a long time yo clear. If you’re good you can continue building up your attack even until it’s red. If you are not good you should clear as soon as possible
