nether fortresses

in the nether i used to find it challenging to find nether fortresses it was fun and an adventure. Whereas i found a secret that i don't think people know about that creates a huge flaw for the game itself. If you stay between x:110-130 and at y:65:000 feet you will find countless amounts of nether fortresses which is causing the nether to be no fun at all. So i have tested this several times on brand new worlds and my friends worlds as well as servers and i get the same result. Therefore, the nether fortresses are not randomised and can be found very easily. And for me it is easier to find a nether fortress time and time again than it is to find a mineshaft. Clearly an issue.
So clearly nether fortress spawns need t be rewritten and randomised otherwise the nether is rather predictable and boring when it should really be fun, unpredictable and an adventure. If you stay between x:110-130 and at y:65,000 feet you will find after time that you stumble upon fortress after fortress. Thank you for reading.
