Some people just ignore the lore. Not that I am against BE receiving San’layn or Dark Ranger customizations either, but there is some lore to why it may not work for BE’s receiving these customizations.
But then they all try and pretend that it is just all RP tools, to most of the customizations, but honestly, there is a bit of lore explanation too with the VE’s and BE’s receiving the High Elf customization’s too.
