who are the best 10 (top 10) players in 1v1?
who are the best 10 players in teamgames?
who are the best 10 players overall?

let's see the different opinions.

Look at the ladder leaderboards.

The ladder leaderboards wouldn't really show the top 10 players and/or team players. They just show the members and their results. Not being a member doesn't exclude a player from being part of the top 10 players.

Personally I think it will be very hard to point out a certain player as being the BEST in such terms. There are dozens of maps, various differentations in team division and so on and so on.
There are just way too many variables to make a good estimation who would be the best in the general sense of the word.

All we have are various players who are deemed by the community to be the good. Which player is best out of this group is open to debate though.
