If you read my post, you see I was mostly referring to high level (more like top 20) play. IMO, anyone not top 50 is basically not high level. Even so, ladder rankings are not a perfect indicator of skill, as anyone who plays enough and is somewhat good can achieve a high rank.
This high level play applies to tournament play, where those advantages actually matter in even match ups.
Are you suggesting we balance a game that thousands of people play, so that 20 of them can be happy?
