That's a great suggestion, thanks. Although the current system encourages people do delegate SP to get gems more easily, but it's worth looking at your suggestion.

The aiming was removed from higher tables like Moscow and Tokyo and still not there. However, now you can find many players in London and Sydney because of the new unlocking system and take advantage of your cue. They'll keep searching for opponents to meet the unique wins requirement. To unlock Sydney, one needs to win against 25 opponents in London and to unlock Moscow, one needs to win against 20 opponents in Sydney. Both tables support the aim-lines.

Hopefully, the new mode could turn the tables in terms of activity.
