On his own releases he's started embedding the subtitles which is nice.. but yes i admit a lot of his rarbg uploads are missing the subs... I generally remux the rarbg ones with the english sub track so it's annoying when they aren't there.. I've had good luck grabbing them from subscene though.

They are re-uploading a lot of RARBG 1080p x265 releases but have are also releasing new movies / tv shows under their own tag with very similar quality and file sizes.
