Playing Mandalore (Pre Vizsla) trying to retake Mandalore, they (Mandalore proper) decided to go support the CIS. Some months into the war the Techno Union has already conquered the Galactic Republic and have landed dozens of divisions both on my core planet and Mandalore itself, to the point where it'd probably be in my best interest to either restart or pull back to Concordia.

TLDR: Techno Union seems kinda over powered
