How do you figure? It's still as strong as the crit bootshine with about 15.3% crit (which is not really that hard to get) and it still beats out Dragon Kick, Twin Snakes, Snap Punch and the buffed True Strike in terms of damage/use.
In a longer fight it's too expensive TP-wise, but how is that any different from 2.0? You still didn't use it when TP was a concern.
Edit - Unless you meant Impulse Drive. And yeah ID sucks now.
