So I just realized that donating troops to clan castles for a war doesn't give you experience , nor does it track it under the achievement. I'm just wondering if Supercell wants it that way or if it's a glitch. Any help is appreciated.
If it did give exp, people would just exploit it for easy exp, since the owner of the war base can throw away troops, thus making more space for more troops to be donated for more exp. Hope that made sense.
