Why is the armor still bad?

I’ve been playing Elden ring since release and my biggest complaint about this game is THE ARMOR IS PRACTICALLY WORTHLESS. I hate how the meta is bull armor with certain talisman when I wish it would be as simple as leveling up the armor and building your stats based on armor stats. I’ve had 99 everything and the only thing that made me seem somewhat resistant was the bull armor meta. Can from software either buff armor or just give us a different defense system besides big shield or bull armor. There are too many armor sets for most of them to be useless. Please tell me how bad I am.
