Eeem these guys aren't reaaally dubstep at all so as Jackmaster said this isn't really the forum for this kind of music. Off the top of my head though id recommend A1 Bassline, Drop The Lime, Tiga, alot of stuff off the Trouble & Bass label, Surkin, A-Trak, Armin Van Helden, Kitsune Mixtapes.
You could also try Baobinga & I.D. always bass heavy, usually breaks but sometimes along the lines of the shit I mentioned above.
Probs the Electro section and Indie/Nu-dance section of beatport
https://www.beatport.com/en-US/html/con ... 86-index=2 will give you a vast selection of artists and tunes!
For stuff close(?) to dubstep but less dark maybe try UK Funky like Roska & L-Vis-1990 or maybe 4x4 Bassline but I don't really know any artists who do that stuff apart from T2.
Hope that helps you out, it helped me to put off my studying for 5 minutes!
