Is there a single argument that will convince you that people don't want floating ASIs just for Powergaming reasons?
Perhaps, but I've yet to see much of anything beyond.
'I want to make X race dramatically weak in the Stat it normally is strong in.'
'I want the highest number possible.'
People dont want to just outright say they want their primary stat as high as they can get it at level 1, even to the point now where not having it is seen as a penalty, a debuff, which it quite literally is not.
So yeah.
People want that sweet +1, which I've been saying for over a year.
No. Not "the highest possible". But:
1) Higher > Lower
2) "What do I get if I go with lower rolls?"
Currently, within the rules, you are choosing between a largely narrative difference (race) and that higher roll. Which results in a huge number of people choosing the higher rolls, and the same old race:class combinations over and over again.
A design that unnecessarily encourages people to make mechanical choices at the cost of roleplaying choices is bad design, in my book.
Fair, not highest, otherwise you would be a Variant Human (oddly enough the most played, and favoured race...hmmm odd that.)
If you dont like race design, thats fine too, most are terrible, but the reality is this.
You are choosing raw numerical power, over any other consideration. Which is again 100% valid and fine, but it is what it is.
People want the +1, because thats what they value most, the power of a +1 on a dice roll.
