Who am I wrestling here?
Anyway, I had some trouble understanding ways and means' latest post. So if this reply doesn't address it properly, that's why.
Obviously, powers should be stronger than stunts. But the narrow focus, versatility and specialization of stunts should make them a non-stupid choice for all characters.
This has several upsides:
1. It presents an interesting choice in chargen, preventing the formation of a One True Way.
2. It provides characters with more personality. A pair of stunts boosting accuracy and stress inflicted can be very different from another pair of stunts boosting accuracy and stress inflicted. Strength is always Strength.
3. It rewards specialization. With stunts, you can build a swordsman. With powers, you can't. You can only build a Weapons-user. It should be possible to narrow one's focus and become better at it at the expense of one's other abilities.
4. It is aesthetically and thematically pleasing. This one is very personal, so I won't bother explaining it.
What these all boil down to is this: if not for the usefulness of stunts, I would have gotten sick of statting up magical combat characters a long time ago. Your interpretation makes things less fun. (For me at least.)
PS: You mentioned that one could use Endurance to defend when grappled. Can you also use Endurance to defend when not grappled?
PPS: Why can't you grapple a zone? The RAW seems to allow it with spellcasting, if Orbius is to be taken seriously.
PPPS: If Footwork was refluffed as Parry Everything, would Might modify Weapons/Fists for its use?
