Defense Training needs work
Bit of a gripe + feedback but the defensive training is extremely shallow. You're immediately put into critical state and a single punch lays out out. If you're in a small playing space it's nearly impossible to make 30 seconds on hard+ where even a fast jab from the opponent can drop you. If you're in a big space, you're not defending at all - you're dancing around the ring keeping distance instead of actually trying anything defensive if you want to actually get the full benefit of the training.
I dunno what sort of impact the stat numbers have on career gameplay, but it seems like there little reason outside of trying to keep your chin strong to even do the defense training...offensive at least has you trying different (sometimes questionable) combos, and Sparring gives you benefits on both sides. Would be great to see Defensive training improved so it's at least fun to do without tanking your stat progression due to a very flimsy OHKO mechanic.
