wow this discussion again.
I voted no, I think inter should have its own league on tus like onl. The only way I can see intermediate working as part of the classic league is if you play bo1 with placement. Many will argue that placement changes the scheme too much (which I know it does), but placement is the only way inter can become a part of the classic league imo.
To those who say "placement takes too much time", no it doesnt, it only takes twice as long as it would to place 8 worms in elite, it really isnt that much more time and as far as I can see this would be the only way of successfully incorporating it into the classic league, although I firmly believe inter does not belong in the classic league for reasons that have already been discussed time after time in thread after thread.
Bringing back TNL seems like the best thing to do if inter is to have a home on TUS, or try "tweaked" inter, bo1 with placement. Bo1 without placement will not work regardless of the map, and without bo3 minimum you cant play inter consistently competitively.
