It's not a terrible idea, but I think that if there were 4 divisions, it would suck if you were a really good team and had to start in the ''wood'' division, but then you would have to wait until the next NHL game if you want to get to Pro division. + I'm not an expert, but, from what I've seen, the number of teams that "don't want to be promoted to pro" is really little. ECL should always be competitive and a 4th division would be kinda pointless imo. If people want to play competitive and casual at the same time, there should be a different tournament taking place parallel to ECL (like the Magic cup).
Also, this level of competitiveness and equality among teams, I think, is almost impossible to achieve for Lite, because every season you get a few teams in Lite that don't know how to skate/shoot/pass and some that could even play with the big boys up in Elite.
Right now ECL Lite is kind of in the middle between being a lower-level, yet competitive or just a plain, casual league. I think the tournament organizers should decide which one they want it to be and fully go for that. I'm all for lowering the number of teams that make the playoffs to 32, because, as everyone has asked for, that gives the teams more meaning to their games and also one less playoff round (6 was a bit too much). And yeah, I get that there will be more teams that quit mid-way during the season, but if a team has the mentality of quitting, then that team isn't what this league needed anyway.
