I may not agree with the strength, but for resilience, something needs to be done to make it worthwhile, but I don't think flinch reduction is the right way to go. some buff is needed, maybe just more HP from investing in it could be a solid start, or to target shotguns and snipers directly, attach some additional bonus that grants damage reduction when taking massive damage in a single moment that becomes more powerful the more you spec into resilience while NOT reducing super damage, I don't know what the scaling would be for all ten levels, but my idea for the max level affect would be that a shotgun blast would only send you to halve health, yes that means you could still be punched out, but at least you would have one more chance to fight back while also reducing the affective range of shotguns because they would NEED to follow up the attack, and for snipers, the max level affect would be that a headshot breaks all of your shields, at least taking you out if the fight to heal, or needing a team mate or a follow up attack to finish you.
