That's basically why koopas decided to hit Argentum. Same with Legion.
Koopas were just getting into O64. We ran a weekend OP on largest alliance in the ocean, and within a week they disbanded and Argentum picked up most of them. The following weekend we basically hit the same targets just under a different banner. The center of 54 was too far a jump at that time.
Legion did the same thing. They took in players from Argentum and from the other alliance we were hitting. Our first OP against Legion consisted of mainly Argentum players that defected..we have just decided to keep pushing
