That's because 2010's ground game is horrid. Two transitions and you are back to standing, standups after about 6 or 7 seconds real time. Submission game is all but ruined. Transition spamming is no longer punished, not only are you likely to get out because of the ridiculously short amount of time it takes to get out, but it actually takes more energy to trans block than to escape, so the subs are gone. And the CPU appears unsubmitttable again. Oddly, this doesn't seem to apply to the clinch where it takes like 6 transitions to transition if the CPU is blocking you.
