Well that seems disappointing as all hell. So if that's useless, then I suppose its just a better playing DOA4 or are there broader system changes that I should read up on? The OP is kind of scarce on the nitty gritty details on the added mechanics.
They're definitely not useless. Especially if you've got a character with a launcher throw and you're in a room with a ceiling <3 Rig.
The game overall feels much tighter than DoA4. Movement isn't as loose without feeling restricted. It feels more difficult to counter, as if you can't counter immediately from some strings. The timing doesn't feel as lenient as past DoA games (although it's not as difficult as other fighters. There are less stuns in the game, so less reliance on guessing. Unlike DoA4, there are lots of natural combos and normal hit launchers. The wall game is back to being a threat again.
This feels more like DoA3 than DoA4. I love it.
