The current reason the perk is not taken is because the legs are the last place a sniper would shoot. By making that area (and the arms) a more popular place to shoot, the reason to avoid the perk is removed.
Though in addition to that either combining Strong Grip and Tree Thrunk Thighs or/and severly buffing the effect of legshots will be needed too. Seriously, leg shots are based on simple END rolls, the one stat EVERYONE has set at 10.
As I can see, raising the crit chance does not help these perks at all:
- Strong Grip can be taken only when you dont need it at all. (ST >= 8, Weap drops rolls based on ST, sometimes even added bonus) To make the perk usefull, the requirements has to be lowered, but then again, everyone with low ST would get it, and make arm cripling useless, regadless of chance to crit. Probably that's why it has ST>=8 requirement, could be a bi tlower though.
- Yeah, this perk is useless if you have high EN, and everyone has that.
Raising crit chance in both cases would result only more damage, not more effect. To solve both, I suggested a sniper perk/rework before, that would affect the resist ROLL on critical hits, making the victim less likely to resist effects, but at the same time would give a higher damage resist to the target, like Finesse. Every sniper was outraged for some reason, but since I don't play sniper, it's ur problem to solve this, GL
