Hi,
I'm relatively new to this game, and registered to this forum just to point out to this issue. I can see there was a lot of discussion going on, in a lot of different threads, but here are my 2 cents on this.
Not being able to use heroes in CWs while upgrading is killing my clan. We basically aren't having CWs since there is always someone with heroes on upgrade, and in casual clan where there is barely enough people for wars, result is no wars at all... (League being exception, thank god for that

)
I've just come on th12 , but th 9-10-11 i played almost no CWs since there is always some hero on upgrade.
Books/hammers don't help/fix this. In a causal clan it's hard to organize active people for all to have upgrades on the same time so that we can do wars...
It is just killing clan, people interest.. I can see this was addressed a lot of times, and it was never action-ed, which really boggles me..
In a strategy game, you aren't able to use basic strategy mechanism (heroes), or use it and punish your progression..
I see this as a big cause to making negative impact on game-play experience and players interest in the game, so i'm really wowed how it was decided to put this issue on hold for so long...
Thank you for listening to my ramblings
