In my experience Alex is a jerk, period. I don't like it when he turns up in a game, but ideally he will spawn on same continent but not nearby - too close and you're in trouble early game, too far and he will have got scary strong by the time you can get to him. And I loathe his UA...
...in fact though I don't normally countenance Genocide, with Alex it's the humane thing to do.
The only time I'm pleased to see Alex is when I play as Greece!
