I've been playing the weekly as I find it really easy, and I wanted to share a discovery I made, this'll get fixed, so use it while you can. The Weekly bots don't seem to know how to CGB.
I support ledging, especially in the Weekly, and I have found that the bots don't often react to moves that are delayed. Land a hit, short wait, get a GB. Have a GB get CGB'ed, small wait, try again, get it. I've saved a couple clips of me and a friend doing the weekly and I'll post them up when I get home and link them here as proof.
You do realize it's all chance, right? The AI from level 2-3 have a set % chance to CGB a techable guardbreak, 3 having the highest. I've had them not tech up to three times in a row, and another time they've tech'd more than ten in a row. There is no trick, it's all chance, or you're just catching them in a heavy startup.
The Video, as promised. For some reason in the first phase the thing cut out when I killed the first Shaolin, but the rest seem intact. PlayStation's ShareFactory isn't the best unfortunately.
