So our local arcade got Ex today ... Been playing it a bit more. The Joker ender feels easier to do for some reason (i.e. super jump w[jA jB jA land 5B jA jA jA jB 3c jB]).
Also, human Gold Burst option select for those who don't know already (credit to LK for suggesting it):
Meaty 2A~5B/2C~6A
So you do a 2A which will either gatling to 5B or 2C (your choice), and if it whiffs due to the Gold Burst, your 6A should come out and autoguard the Gold Burst. You can't actually punish the Gold Burst on recovery, but you're in slight frame advantage.
