I think it looks like a lot of effort, and I'm not sure what the gain is.
What part do you see effort in? Which option does that apply to? Is restructuring the game to one of the Alternate Roll Methods the "lot of effort" part? Or are you saying that even saying a SNA grants +2 to each of its dice is too much effort? Can you clarify?
As to the gain.
The intent is to use the same general Attribute Scale for everyone since all species get the same rough net +5 Ability modifiers. That doesn't work when throwing in supernaturals into the mix. By the system as it it stands, defining something like a Giant (alla Fantasy Craft style, not D&D Hill Giant style) as a PC.
I want Supernautral Attributes to matter and to be species defining.
As stated above , if the scale remains the the same I want a Giant with average STR 3, to feel more powerful than a Human with average STR 3. Simply because what is average for a Giant is still superior to what average is for a Human. An average Giant should be able to lift more, perform SR based tasks more easily, and cause more physical damage than an average Human. I would rather do this without having to simply throw more modifiers at the Giants STR die pool, considering its a lose sum game due to Pool Caps.
Which do you see as working better (and closer to the game's balance):
* Supernatural STR dice increase in dye size to d10s.
or
* Giants all start with +8 to STR?
