People legitimately raiding your oil is unfair, but purposefully targeting one player to continuously raid them is fair?
I had nothing to do with it. I can't chose my targets. I was just nexting and raiding. And after attacking few similar bases I was like - hey I already attacked this base this mornig. It's not my fault that I've nexted so many times or there were some matchmaking problems
I understand how those games work and the idea of raids but in case of demolition -
obviously we are talking about different definition of balance 
For me - balance means attacker vs defender or attack vs defense BUT NOT attacker vs attacker retrain time.
Or another words:
1. If a guy can attack me with planes - I can use air defense.
2. If a guy can use tactics like sabotage on my mortars - I can space them away.
3. If a guy can use tactics 4x demolition on my 4x mortars - I still have other defenses.
4. If a guy uses raiders and wall breakers – I can use defenses and few lvls of walls.
BUT
5. If a guy can use 4x demolition tactics on my oil refinery – HOW CAN I COUNTER DEFEND IT? Oh, I forgot – I can counter defend it because attacker have to retrain his demolition tactics

And u call it balanced

This could matter in the board game one vs one. But here we have thousands of players so I don’t care that attacker have to retrain his tactics because there are next few thousands attackers waiting in line to steal my oil using same tactics because I don’t get any peace treaty after that kind of attack.
AND THERE’S NO WAY TO PROTECT AGAINST demolition on oil refinery. They understood it in Clash of Clans like 2 years ago, so it’s just a matter of time until devs of Dominations understand this too

Or maybe we should call it
Demolitions
And I also don’t understand that amount of attacks in a row. It happens to me every few nights. I can sit on full storages of gold and food and large amount of oil and rarely be raided. But then one night similar amount of resources and up to 15 attacks in a row without a peace treaty. Attacks stop when I try to log in the game in the morning or hopefully got some peace treaty. It’s also sick
Now I stay in copper or silver league and don’t care about medals. I protect my oil refinery with many lvl of walls from all sides, this should prevent it from raiders. But not from demolition
