Armour break should be limited

There is not many defence layers a player can get against pure physical damage. Armour is the main poster child of physical mitigation. But with armour break, armour becomes very unreliable. This is because there is almost no visual indication your armour is broken, and because armour can only be broken by physical damage, the amount of breaking increases exponentially. So often even against trash enemies you get completely armour broken in 2-3 hits.

Often then not being fully armour broken also means you take up to 1000% more damage against all damage. As if you are scaling armour, you also take armour applies to ele/chaos.

If it could be limited to maybe 50% of total armour. Or something of that nature, it would still really hurt. But it could be manageable, and if you do bad decisions you could maybe even use armour as a defence against damage.

On a sidenote, why is vulnerability in acts -12k armour? Who has 12k armour in acts?
