Players that are online for 2+hours straight should get a buff that gives them an lp gain every half hour for a decent amount.
If the player logs off they just get another 2hour cooldown before the buff starts again.
This will encourage people to stay online and discourage for people to autolog off like cowards or get put back on cooldown for the buff.
Over time the buff should get multipliers added to make people want to stay logged on.... forever.
