fix ES by letting it take pre-mitigated damage [suggestion]

Since ES can go to such high numbers it would be interesting to move it to pre-mitigation. meaning damage would be taken by ES before it would move to standard mitigation calcs like resistances. It would be even logical since its a 'shield' and not actual HP. This would cut effective 'hp' of es by 4, and maybe it would help balance things out.

This would make ES completely useless after like Tier 5 waystones.

ehp of ES will get nerfed one way or another. While cutting it in 4 is drastic it will allow CI characters to completely ignore resistances which would be very interesting for gearing and potential build opportunities. I'm very usurious what would come up with this change
