I don't have a philosophical objection to Club Wars like the others, but I wouldn't mind seeing it go away. Like others in this thread, I experienced major delays in the game since this feature was introduced. If you're going to have wars, why bother with a cooling-off peacetime? We can't complete war-related challenges during peacetime. If you insist on having a peacetime, what is the point in restricting us from collecting war supplies? Plus, war supplies are affecting my storage capacity, so either put them in a separate storage facility like Omega items or make it easier to expand storage capacity.
In the words of The Boss, Bruce Springsteen:
"War! What is it good for? Absolutely nothing!"
(yes, I know it was a cover, but his version was best)
