Yeah, that’s great, but it doesn’t really answer my complaint that the default out of the box is 30%, which isn’t very intuitive.
In UX design, you always have to be mindful of precedent. I once had a boss force me to try alternative symbols to show a player that an NPC had a quest for them. The standard is an exclamation mark, and while I agreed that probably wasn’t a great symbol, it had been done so many times in so many games that to change it now would just be confusing for the player. We explored a bunch of different symbols, and guess what? We used an exclamation mark, because every other symbol gave our play testers trouble. The last thing you want a user to be doing is trying to figure out stuff that should be super straight forward, like key tracking.
