Played about 99% infantry upto this point want to try something different. I have a bunch of unused certs and I am thinking about trying the Max units, never really used then much except for the dual burster a few times. Not wanting to waste certs what are the best things to cert for: AI : Close quarters/breach (I like my HA outside) AV: Open Field (Seeing a lots of TR/NC tank zergs on Connery) Got about 1800 SC and 4500certs to play with.
