Very nice change. I think the champions league will be much more interesting with this change.
If the top-ranked player loose in the moment 36 rating points in one match he can get this back in 3 matches (+10, +10, + 20 because of winstrike) - if he now get only 3 points he need 12 matches to get back his old rating.

But I have one question:

"once players reach the Champion I league at 4700 rating points they will no longer receive a win-streak bonus or have a minimum rating increase for wins. "

If a player reach 4700 he will loose the winstrike and the minimum rating increase, but what will happen if he fall back under 4700 - will he than again able to have a winstrike bonus and the minimum rating increase or will this change be active until end of the season ?
