but putting in a randomiser for one or two seconds for the waves - no. Just no.
If you send with existing methods, there's a chance that waves will mess up = snipes can happen. They want to artificially mirror that even though they automate waves. Which is a good thing. Part of the excitement of launching attacks is worrying about getting the waves out perfectly, and so on. Mindgames between defender and attacker if some attacks are sent perfectly while others are not - and if they are cancelled if not in same second etc.
As a defender, I would also hate it if attackers had guaranteed perfect same-second waves, with no chance of sniping.
Why would anyone use this instead of existing methods?
People playing from phone/tablet. People playing on Mac. People not at home with their usual setup. People with poor internet. I wasn't a fan of an automated wave builder, but I think this solution is good. It's still viable to launch waves "manually", but the people I just mentioned will be able to participate too.
