Generally, it is a subjective thing and I feel the way the map progressed into being the way it is today was always intended, I don't think a lot would be different even if I did go back and tried to re-mod the map.
As for 1.5 vs 1.2 SV, the 1.5 velocity was intended for sections that only had 1 or 2 sliders max as an emphasis, while the 1.2 velocity was intended for entire sections of the song containing a big chunk of notes and sliders.
All I can say is thanks for the care and attention if they're there, my main problem is time and I happend to have had a very little amount of it for 4 years, this map in no way reflects me trying with all that I've got, it's unfortunate to me to leave this map as it is without any real improvements, but it can't be helped, I'm giving it one last shot in the next few months and if it flops I'll leave it to the Loved team to pick it at some point in the future.
