Lots of empty space here.
Fill up the new ED and you could have enough stuff for both a melee and a caster.
Doing some math, we have 24 points to spend atm.
With the increase of ED to level 10, we should have 16 more for a total of 40.
If the left side of the new divine ed is str/wis, then players could spend 2x6=12 points there.
If I was a dev, I could pack up 28 points to spend on melee and 28 points to spend on casters
all in one ED. I could do it, can you?
