Actually, Boxtorrents has Rave Master. What threw you off, was that it was in its alternate name. Rave Master is also known as Groove Adventure Rave. You can get the full series of Rave Master (Groove Adventure Rave) subbed by Soldats and Choco-Fansubs from here. You can also get the first 4 episodes of Rave Master in better quality subbed by Anime-4ever from here. Hope I could help.
