As you win (especially against teams with similar HR), your TR/PR slowly raises, but it takes a hell of a long time to raise it up to anywhere near a 2000+ level, or at all for that matter about wow powerleveling. Not only that, but as the system tries to pull you towards your 1500-1700 HR and you are a 2300 TR/PR team, you will gain very limited amounts of TR/PR until it has risen to a number that is close enough about cheap wow gold. This would not be that big of a deal if it was not for the fact that because of this HR being lower, your 4-6point gains from wins will be matched with 10+ deductions from losses. This means that if two 2300 level teams duke it out and trade wins, both teams will start to gravitate towards their say, 1800-1900 HRs even though they are trading wins. It becomes a lose situation until all players on each team have brought their HR levels up about wow powerleveling.

If the one of these teams were to make a new charter, their HRs would stay at an 1800-1900 level, however, their TR/PRs are now at 1500. That means that any wins would yield huge point gains as their TR/PR numbers will be pulled towards the HR level of 18-1900. Once they hit the same level with their TR/PR, then Wins/losses would be equal, like the old days of similarly rated teams winning 15/15 or 18/13 etc about wow powerleveling.

Now since Blizzard started everyone HR at 1500, high rated teams will again, be losing a lot more points for losses than they do when they win until they spend hundreds of games proving their worth and raising their individual HR levels. It is basically capping and preventing those players (unless they never lose) from increasing in points. Obviously this would have been much much better had it gone in on day 1 of season 5 to get more wow powerleveling.
