They wont be many people from NNNL joining and playing TUS single just because Intermediate is available. Intermediate-only-players like Joschi, Kayz, Koras, chuvash, Fantomas, jule, Antares, Viks, FaD, Dario etc. wont playing single TUS coz they always have to play an oppenents pick, which scheme they dont know / like for 90%. And Intermediate players swear at modus bo3 or higher coz of balancing some luck / bad luck. But we cant play Intermediate ina bo3, would take to much time just for one single pick. So they dont enjoying a Intermediate played by only bo1 - even with cave it is not good balanced, but better than on isle, tho.
Some guys from b2b playing single TUS too, but many of those b2b-members u dont really see at TUS (Wormfood, KRD, Ramone, surgeon, M3ntal, skime, Krezo, lacoste, Prankster etc.). By putting Intermediate to classic league wont help much to get more acitivity. So I just vote, like before, to
put Intermediate into
Free-League.
Current schemes are perfect for Classic League. No need to change there smth.

btw, NNNl-Intermediate-Scheme should be used in TUS too, doesnt matter which league type.
