I'm confused as to exactly what problem this is addressing. The post doesn't really call it out explicitly other than saying "...while also solving some problems with the current ECR system". What are those problems? Is the issue that people are playing too many matches a day [causing rating inflation] or is it that new players cannot figure out the -1% of ECR per battle drain or is it to put a new DEC sink? I'm not really for or against it as there are obvious pluses and minuses, I just like to understand the 'why' they are making the change.

It does seem to favor multi-accounting in a serious way. Guess I'll spin up my alt account to take advantage...sure everyone else will do the same...
