Is Calvar-ion broken for early-mid game irons?

I decided to go for dragon pickaxe on my iron, 70s combat. From this I’ve banked enough dragon bones for 70 prayer, enough oak planks for 70 construction, 7000 gold ore (haven’t done the math on what that’s enough for), tons of mort more fungus, limpwurt roots, wines of zamorak, ranar weeds, over 500 uncut rubies and 200 uncut diamonds, 150 sander serum, 1000 supercompost. 1800 magic logs. Ring of the gods (+8 prayer bonus is so insane for range and mage all throughout mid and late game).

Also one of the biggest upgrades is I have 22 healing food now from dark crab drops and super combat potions to save inventory space, also ranging potions if you don’t have the herblore level. All you need is dragon defender and dragon mace for like 1 minute kills with all of these insane drops. It seems like you can skip so many iron grinds if you just camp calvarion.

I have been pk’d there maybe 5 times in 800 kills? It’s insanely easy to get away and most people that enter can’t hit me at a low level. All-in-all I think calvarion is majorly overturned.
