Two points.
1. The current system only looks flawed because the team in 8th isnt that hot (whoever it is in the end), but by that token they wont get anywhere.
However what if the team in 7th/8th was only a handful of points away from the top 4, having been extremely competative and only lost games by a score or two due to poor luck or contentious reffing decisions? Would it then be so flawed?
2. People are viewing the playoffs entirely in the wrong way, now this is due to Sky pushing it in the wrong way but the race for the league leaders trophy is like the qualification rounds for something like the World Cup Finals (soccer wise)
Through the regular season the competition is to get into the finals, the finals then decide who is champion and the playoff scheme weights the rankings accordingly, like a seeding process in pretty much every other competion in the world.
