I and several others in my alliance stopped warring shortly after the rebalances began and started playing other games.
Raiding is a chore now, and unless you raid for NTG (the only reason I had to raid even before the stupid rebalances), you can't compete in war against high level CWA bases, so there was no point anymore.
If raiding were still viable and still fun then wars would still be fun, too, even if a little tougher (I can still 5* after the rebalance, but that's not the point). But they're not, and it isn't.
Our alliance is struggling to fill 10v10 wars now because so many people have quit. What do you think that's going to do for matchmaking, eh?
