Just something i've been thinking of, something to add in abit of build diversity to rdd rather than just seeing bg/rdd or paladin/rdd.
The idea.
Have which scale color you pick, decide what the 'main' stat is that rdd gives so instead of just giving strength it could give..
Dex.
Int.
Wis.
Con.
etc,etc. The idea isnt to give rdd /more/ power with this, just..open up more build paths for the class.
