I don't think it matters much. Yeah it might matter for predictability/unpredictability but this year everybody thinks than Denmark and Latvia will decide who's going to relegate anyway, so the last game of relegation round will still (if no surprises occur) decide the relegatee. Yeah, there won't be much point of having, say, theoretical game Swiss/Slovakia vs Czech R. but isn't it like that usually? It was like that in 2010, yeah 2011 and 2009 were different but still i don't think it matters much...
What's better though is that in lower divisions teams will be able to play closer games and we won't see 10:0 for Germany or somebody else on daily basis. This year in DivI A Germany had only one such game and it was a good German team and the tournament was really interesting. Last year's Latvia's U18 DivI tournament was one of those where there was no point for us to really play vs teams we had. Had we better opponents, maybe we wouldn't move up but at least we'd see what our boys are really capable of.
This is bad for smaller teams like Latvia,Norway, Denmark, on the one hand, as now our possibilities to play in the elite, among the big boys lessen but at least we have better competition in Division 1
