T4 land
I think it's needed to make few changes at this point so fatboy or megalith will finally focus a monkeylord when escaping.
I would suggest for all the land XPs the following priority :
T4 > ACU+SACU > T3 > the rest > buildings
CZAR
CZAR has a little bug appeared few patches ago. It became a no autofocused unit. so for any other single scout in the air, the AA won't decide to attack the CZAR. (that's the main reason people found CZAR super buffed recently)
