Many players have the problem of being drafted from high level HC's (level 14, level 16 or the Atlantis). To avoid getting drafted follow this simple trick
1) find a player of your alliance who has a city nearby.
2)send your troops to his city and also tell him to reinforce your city(optional).
Reinforced troops can not be drafted both your troops and your friends troops will be safe from drafting. Also if you keep the troops reinforced into nearby city, you can recall them quickly when you want to attack anyone.
