Waow! Wait a second, y do u hate hoppers? Isn't it just more donations for u and a happy camper (gets troops) instead of an angry u and a sad camper (doesnt get troops).

If you give your best troops to new members, and they leave, that's your bad, not theirs.
Give them archers or minions. Make them earn anything better than that.
