My job as a GM is to set effective guidelines. Which I'm doing by setting clear house rules.
Actually your job as GM is to craft the mutual story-telling experience, which is generally the best when least confined by rules. The notion that nerfing cyberlimbs, which while janky are not at all broken, creates a better experience is just false and even lazy, when it could be solved by just speaking to players as GM. And the notion that any human (even your 7 REA + 4 INT + 4 Gym sammy) could leap (on average) 5 meters (a full meter greater than any recorded human ever has, when they still recorded that type of thing), but conceivably 7+ depending on Physical Limit (which is wayyyyy outside the realm of physically possible for a humans physiology), from a standing position is just pure ridiculousnessessness and not good for storytelling in the least. Why can't you make that jump when not having a grenade shot at you?
Damage in a crash, whatevs.
And with touch spells, I understand Magicians were spanked with the nerf bat, but does making up a nonsensical mechanic (what does Magic and your Skill at Sorcery have to do with laying a hand on someone) serve any purpose other than to coddle your own personal feelings? I doubt it.
The Mystic Adept stuff has been hashed out ad infinitum, and I know which way I'm going to go (which is with the official ruling).
And I said, Hotpatch is a given.
