Well, after 3 seasons of sucking, the team is surely becoming good anytime soon. If not, the league should just consider changing the GM as well at the same time. I think the benefits of that is, first of all, no team will be in a position to be hatred for a long time, we see new names/color scheme and makes the league less "the same old thing" over and over, plus, lile you said, rewards good vhlm teams.
Also, if we create new team names/color scheme, we could test them in the vhlm and see if they are popular. As, for an exemple, would be interested to join brastislava if they had a chance to join the VHL. The color scheme was great as well
