[Autumn]

The higher a scaling gets total, the more it ends up , this is why a Brawler's Glove ends up getting upwards to 145-155 SWA on extremely high STR builds, this would mean that pure STR scaling weapons would benefit far more than the split-scaling weapons do, while 2-hand currently compliments pretty much any build at the current moment.

Not to completely discount the above poster's points, but we would see the likes of Rebelling Longswords/Brawler's Gloves/Axes completely take over the scene, given they would be able to reach upwards to 170 SWA with a full dragon king set, I already think that STR is the highest scaled stat in the game when you do account for dragon king pieces.

It is a little strange that bows are better at the moment when dual wielded, though I don't think I've ever seen anyone actually physically use 2 bows and instead it is them RPing them both as 1 singular multi-purpose bow usually, and even though the STR scaling bows often see little usage, this change wouldn't do much to fix that issue given that Arbalests are required to dual wield to make use of many of their functions, barring of course Arbalest/Monk's janky interaction with mixed martial arts.

The split scaling sword/axe/spears would be the nerf of this change, and they already have the advantage of having more stat points to spend around due to not using strength.

This is true for high power split scaling weapons but generally is only the case for the split scaling weapons that go for stats you'd have used already, stuff like SKI/CEL/DEF or VIT end up being highly contested for stats and often make you able to invest up to 40 STR with a decent SWA amount thanks to 2hand. But the likes of a Shine Sword or Magical Nova nowadays would absolutely fail to compete, given they rely on unreliable stats that you generally do not want as high as your SKI or CEL.
