I came after wars were a thing so im noob to this. What do wars even give u? Why do people like it more then the partys that happen now?
From the gaming perspective, there's hardly any difference between wars and parties except there's no repeat action tab in wars, which is why you have to tap your screen more than you do in parties, and they have different payout structure.
Because it is fun, challenging, involves skill, luck, teamwork, tactics, etc. none of which can be said of parties. also the cash is better than payout from parties.
Wars have more tension and excitement. You build great friends (and enemies) from them. It's a great way to test your build with all the parties you do to earn for your build. Parties can be pretty monotonous. However, I think a good balance of both works.
No. They just require a certain number of players to be on. There is no coordination. Nobody even says when they'll be hosting the party beforehand, and asks for everyone to log in at that time. That would be a minimal amount of effort which is missing.
