Is Conflux a broken castle?

Conflux is great, but the ban on upgrading monsters of levels 1, 6, and 7 slightly weakens Conflux, and playing as it becomes less promising!

Believe me, the prospects are very good. I am ready to play as Conflux with a ban on upgrading levels 1, 6, and 7 against any other Castle, and I absolutely don't think that anyone will have an advantage over me because of the bans, but rather the opposite. The main thing is to have enough ore. What does upgrading the first level give you: fearless fairies? So, killing hordes with one fairy and a ballista is not for online play; the unupgraded ones are already fast, and they have a starting speed of 7, which is the maximum after the Swamp, where winged heroes fly on flies.
Level 6: what's wrong with the unupgraded psionicists? Slower speed? 10 less hit points? Or do the upgraded ones have complete magic immunity? So, what I personally consider a real cheat is the upgraded psionicists. Speed 9, complete magic immunity, and they attack all cells. The unupgraded ones are no longer a cheat, but they are also not weak, as I understand from your statements.
Level 7? From my experience in online games on random maps, I know that it rarely comes to upgrading to level 7. And even if it does, the birds take it with numbers. In addition, if it has come to upgrading to level 7, then by that time the birds can already gather so many angels and build so many hives that it will be a strong, powerful stack for you, and the birds will be for support, first speed, and blocking enemy archers. Which Castle can boast that, on day 121, without mass slow, it can have the maximum number of griffons, besides Necropolis and Dungeon? So, 4 unupgraded birds, 5 unupgraded psionicists, air units, and the rest of the meat can do this; the main thing is to have at least some reserve (it depends on how many air units you have at the start; if there are few, then there may be a reserve of them). This battle is not entirely easy, but it is quite possible if you have enough money on day 121 to buy everything, and the air units with psionicists and birds are strong.
Everything I wrote implies playing on a random map with 160% settings
