I'm really wanting them to work on the ground game a bit more in DOA5LR. Kasumi can deal with it, but she has to play the guessing game more. That's what I liked about vanilla's ground game, despite how dumb & braindead force teching setups were. You wouldn't be lying on the ground constantly without having to worry about being at a disadvantage. There's some characters who can play the ground game consistently & then some who can't. Rig is one of them who can do it consistently. The invincibility of the ground causes ground attacks to whiff for a lot of characters. Even when they've been on the ground longer than like...3 seconds.
When I have an opponent on the ground, I shouldn't have to worry about being hit out by a wake up kick. That easily negates it. Sure, you can hold it, but that's a part of DOA. The part I do like is the hard knockdowns. If wake up kicks weren't the way that they are in the game, then I would be fine with it, but it's not to where characters are consistent in doing so.
As Kasumi, she has things to beat out wake up kicks & has force techs, but at times, I don't real that it's worth the risk. More often, I find myself using 4H+K when I catch them lying on the ground than I do 9KK's setup because of how players immediately tech after the hard knockdown. Even after a force tech, there's always the possibility of getting punished by a wake up kick or tech rolled & then throw punished (which is also a part of DOA).
