[@PrinceAlexus] Hey yeah
I'm using loads of different variations so I can give as much variety to the attacks as possible.

Plus because I need to make sure that none of the stats are OP certain dice need to be different for different tests.

D4 true could be simplified to a D12 divide 3
1-3 4-6 7-9 9-12

I see your point but I would try to bring that down, and try and keep things as uniform as you can. 

I play some tabletop. 

And one manages a lovely human with a bayonet, to the equivalent of 2500 ton walking bipedal warmachines all on the lowly D6. 

Just consider the whole multiple and divide the D 6 can give you. If you seriously want people to use it. You need to make a system with easily accessible parts.
