It was fun until I hit lvl 50. I had not been raided until lvl 50 and it was a surprise that all of the building of defenses and researching the buffs to improve those defenses were for nothing. My defenders were inside the compound, behind upgraded and researched doors, behind upgraded and researched barriers, traps upgraded and researched, wearing uni armor, uni headgear and long range uni weapons ... I lost all my survivors every raid. Out of the six raids, raiders only lost 1 attacker total. Six months of play to learn you cannot defend your compound at all. It is a shame raids favor the attacker that much and they are that so easy to do.
