Also, as if high ground needs to be buffed - it's already ridiculously overpowered and definitely is not in need of any help.
I agree with what you're saying in your first point, but range can definitely use some work. Certain spells are balanced around having more or less range than other's. When you just go and say,
"all longrange spells have a range of 60ft."
You are killing variety while also nerfing and buffing spells, when you could just make corresponding changes to the ranges, based on the percentage that you are scaling down the map.
Also if high ground is the issue, then base ranges could be increased and high ground benefit decreased to compensate for making ranges not terrible for even ground.
