Where's the Romeo & Juliet hairstyles, then?
Never said we had them all (but they're on the way), but we've got a plenty from G20 and plenty of region exclusives, tons of colors that are not available in any region, including custom colors for pets (see Shire colors).
I'd say you have a much better selection here, especially since you don't have to pay anything for any of them.
is it really that hard to remove the HP cost from windmill?
You're asking if it's really that hard to modify code that was already compiled into native X86 without the source code to re-compile it.
Basically, that is modifying code at the CPU level, in assembly, which is the lowest possible level it can be. No, it's not easy to modify and it's definitely not easy to understand Mabinogi's gigantic codebase (probably about 20,000 files+ in source code) especially after it's been stringed together by a compiler in order to add the new features you've suggested.
You have to remember that those features literally do not exist in this version.
For Windmill specifically, it requires modifying the SkillD library and NOPing out the operation that reduces player HP. Not hard for an experienced reverse engineer, which we have on the team; however we do not want to remove Windmill's HP debuff because it would greatly fuck up the balance.
