I'm looking for some information on the current state of clan vs clan war and how people would like for it to work. For this discussion, please consider a 15 member alliance FSing another 15 member alliance halfway through the round. What are your answers to the following questions in your version of ideal, balanced clan vs clan warfare?

1) How many kills should they get in the FS?
2) How long should a CM rush kill take in seconds?
3) How long should a non-CM rush kill take in seconds?
4) How many turns should it take to kill a country?
5) How many additional enemy turns should be needed to counter a single turn used optimally by a stonewaller?
6) What is the biggest balance issue that should be resolved?
7) Is the only acceptable outcome a tag kill?
