Okay, so for now let’s assume you were in the 315ish range (that would give approx 30 levels i think?).
Sounds good, not a lot of people got the ability to upgrade their farms. So don’t sweat it. L345 is no longer the same as L345 was before. It’s completely different.
Your dragons will be actually BETTER than your level. Forget about what your dragons were vs your old level. Forget about it. The calculator should have told you that you are now able to receive ~3 den levels if i’m not mistaken. Therefore your dragons are technically better than before.
Keep in mind that if you hit a L315 prior to this change, then hit that same L345 base after the change (your same level) they didn’t get any stronger at all. It’s just a value change. So hitting actual bases are identical (yes invader are tougher, but thats another point).
You are further ahead. And they unlocked new den levels that pushed you further into end game territory. FORGET ABOUT NEW LEVEL VS OLD LEVEL. Forget it, forget it existed. You have a new set of data to compare it against.
Say you and 10 of your friends were all L315 before. They are all L345 now with identical bases, and better dragons. You can defeat them more easily, due to you having higher level dragons.
Your base can’t be upgraded at L330 anymore, that requirement went up, as indicated by the charts. It went up about 85% of the new player level scaled amount.
No idea why you are getting so upset about this, it actually works in your favor if you stop walking around with blinders on and only looking at player level.
