Also if you start hitting out other opponents than you will start earning 15 trophies instead of 3 unlike the rest of the player playing the game.Especially top 4000 players.They only find opponents worth 3 trophy and only on rare occasion see any opponent offering them more than 3 trophies.
Which unfortunately I haven’t seen in any of two accounts I whole Heartily support new trophy system as now I can still enjoy the game without being massacred by other players who are always attacking me for 25 trophies,ignoring my defense system or ignoring my defender .
But this morning those opponents are now forced to destroy towers and some of them are losing but I am not gaining much from that but it now better than to lose 16 trophies for 76 % completing a base.I still have to fight to earn trophies at least 150 battles in a day.
Also I don’t approve of what you are doing because it is cheating, grinding gems by keeping low Ascension level and maxing out defense.
I know this because the very same thing happened with me too on my new account two months ago. I too maxed out my defense at level 40 till 65 and I earned more than 5000 gems in just one month and I am not kidding this is cheating.(I never did it intentionally but a side effect of keeping maxed out defense at low Ascension level.My intention was built a tough defense to prevent other players from taking islands where my heroes are and also to prevent trophy loss instead I started receiving gems .)
My friend your base is being attacked as you are at low level.My base earlier used to be raided at least 84 times a day and I am not kidding at least 84 times a day.
But as I leveled up my base started receiving less attacks(now it is mostly between 40-55).Also no matter at what level you will play your base will always be attacked by other players as long as you are not inactive and your trophy count will never go below 0.
