Which route will iconics in the future take? Basically, PDK is equal to or better than humans. They get every human advantage with a couple of extra flavor stuff. Even if you don't use that, they are equal to humans.
Bladeforged are the same to warforged. They are mathematically superior.
Sun Elves is a bit more iffy. They are conceptually different and utilize different weaponry and have a different focus from regular elves.
Shadarkai have no real comparison as they are their own race, so again, more in line with the sun elf: different flavor rather than obvious superiority.
Which direction do you think iconics should take? Outside of needing to LR +1, I'm not sure its a good thing that if you have money, pdk > human and bladeforged > warforged.
