CW: Allow new war search and preparation to commence while existing war unfinished
Pre-(r)amble: Clan wars are where it's at. One requested feature has been the ability to resign a lost cause or end a war sooner when it's a whitewash or is otherwise a massive mismatch of skill and/or size. Another requested feature is the shortening of the prep day to 23 hours or something similar, allowing for clans that war 24/7 to commence wars at around the same time of day each war.
My view is that the first view isn't workable because of the logistics/unfairness of having some players miss out on loot opportunities for having a war cut short on them. The second is probably refused on the basis that different people have different timezones and there might be that one player who only gets to participate in that one hour that he's commuting (or some such logic).
Idea:
Allow a new war search/prep during war phase. Is there any real technical reason why a clan search couldn't commence why an existing war is underway? It would combine well with a feature allowing players to opt out (or be opted out by a leader). It allows either team to start focusing on the next while the existing mismatch plays out. It allows leaders to better control the starting/finishing times of wars. It reduces the time between wars for excessively active clans.
TL;DR: Allow new war search and prep to commence during war phase of prev war.
(Also allow war opt out and leaders to force opt out specific players prior to search, and upgrading heroes in war)
