Its hard to get 100 hit not 300.
In this three days I have only 4 SEG encounters.
I play all day and have 4 Event Card who increase encounter rate of SEG but that doesn't help.
But because I have friend who encounter it a lot I have 22 win over SEG.
I also have 1,862,364 Event SED.
Maybe because I'm the free player. I don't have another explanation.
