There are only 2 things that could cause me to stop playing:
1 - No players to play against
2 - Something that would kill variety altogether (making so that only 1 or 2 builds are viable)
So far, I'm very happy that FFG is pushing #2 very far away. I see a vast array of builds in my area from people who like synergy, swarms, falcons or HLC wrapped ship. I like the feeling of not knowing what to expect from an opponent and I can spend hours in my head building or combining squads, which makes my days entertaining, even when not playing (I admit, that sounds a bit crazy
)
