Yea, the system-agnostic monster generator is a better way to go for sure. Its simpler yet more flexible.
I use Scale quite a bit, just to add a bit of flavor to things or flush an idea out. Lets say I am making a random quest, and I roll "Fetch Object". Ok, what is this object like? I'll roll 1d10+1d6 on the scale table a few times. If I roll 8:Style, 1, that means whatever this thing is, its ugly. If I roll 2:Durability, 5, then its pretty solid. Maybe its a shield made of bone? As an added bonus, I can roll the detail check, maybe I roll Favors NPC. That might mean someone is looking for this shield, and I can get a hefty payout for retrieving it, whereas if I rolled Focus Plotline, then maybe that shield will protect me from whatever weapon the big bad guy has.
I use it with the treasure table too. Maybe I open a treasure chest, and roll 4,5,3,2: A crafted leather brooch. Rolling on the scale table and getting 4,6 might indicate this brooch has some sort of high-level power associated with it, like it can cast Fireball or something.
Or roll on it when entering a settlement, getting 1,1 might mean this settlement is very newly developed, and might have plenty of work for outsiders. Or getting 9,4 might mean the settlement has decent quality shops available.
I like how much value a small table can provide, its fast and sometimes more evocative than the Description table on the inside.
