Your assuming people will suicide to get free points if we improved the reward system. Even if this is the case, it would create a better environment for those wanting to play LMS or CW, as these would be populated with people (even if they are just wanting free points).
Secondly the hotspot system you said, we already have a 'win 10m twice a day LMS' system, however straight after these games, players no longer remain due to lack of motive to stay.
I think a poll system would do justice to see whether the players would actually want to play LMS and CW with better rewards?
