There should be an option for a squad to surrender and end the war. There have been many times when a war has had players not able to attack or not on the game to attack and didn't request troops for the war defense. Why have both squads twiddle their thumbs when one side has decided that they have had enough?
It has been suggested many times before. I like the surrender option. I have been in many squads where we just get matched with mega opponents. It is naive to suggest you use it as a training exercise. If you have done it many times before and just want a proper, fair matchup. This is the biggest singular reason that players quit the game in my view ie unfair matchups. When it is not fun, we walk...
Sure, why not? Surrender is definitely an option. Maybe we should add a diplomacy menu too? And a blackmail or extortion option? 'Pay me 10,000 CB a day and I will always skip ypur base' - Mafia style "protection"
I don't think you could reduce the reward for a surrender win -- too easy for the losing squad to be bad sports and deprive the winning squad of a reward they deserve.
I also don't think the option would be abused, though. You'd have to enter the pool, get lucky to be paired with a squad you know, wait a day for war prep to finish, agree to surrender in the hopes that they'd make it up to you at some future date. Seems like there are more lucrative loopholes to abuse if that's your style.
