Alternative Structure And Stress Rules.

This is just an uploading of an Alternative Ruleset for Structure, Stress, and Bracing, aimed at making bracing stronger against more accurate and multi-attacking enemies, (you know the culprits) and for tables looking for a more evened out  damage penalty. Structure has been reworked to make mechs much less likely to immediately become useless or blow up based on 1 or 2 unfavorable attacks or bad rolls, and stress has been reworked to  A) lessen Exposed-into structure punishment loops, and B) expand the potential list of consequences beyond a simple impaired, exposed, or "blowing up after an arbitrary amount of time."
