Alright. If I doing it too slow, show me video, where you guys can block wakeup after 2134 without tech roll. With tech roll of course it would be safe, but you cannot say to your opponent: hey, don't do tech roll after 2134 comboender. It's simply unsafe, deal with it.
OMG. You don't understand. WAKEUP without TECH ROLL after you knockdown your opponent with 2134 ender is MUCH FASTER. In the OP I see only tech rolled wakeups. That's why it all safe. Just go in practice mode and try it. You cannot block wakeups in this situation.
