I was inspired by tgrant to create something.
What do u guys think of these?
Corner Meter:
I think that if you're stuck in a corner, there is the quick side step that was inputted into mkda which could somewhat manage to pull you out of a stuck corner, as in mk:dcptn, they might make whatever corners most people would end up getting stuck in to be multi-tier breaking through into a new room. However, if you're really stuck in a corner, and sidestepping doesn't help cause your opponent just knows how to stop you, I think that there should be a Corner-Meter. This Corner-Meter should increase as long as you're in a corner and you're either blocking or taking damage. If you're beating your opponent and you're the one in the corner nothing will increase to your meter. Once your character's Corner-Meter fully charges up, assuming that it shouldn't take too long, your character will quickly grab your opponent and switch positions making them the person in the corner. And we all know, that we do not like to be the ones in the corner, so it's best to just stay out of the corner with this inputted into gameplay, and especially with stage fatalities and all usually involved around corners, noone should try to stay near by corners.

The Weapon Meter:
This meter will mostly decrease most of the time, as each time your weapon comes in contact with an object or your weapon is used as defending yourself. We all know that without a weapon, if we block, we do take a slight damage. But if we hold a weapon, instead of you taking that damage, your weapon would. So, you can't stick to a weapon all the time cause it will eventually wear out. But you can still manage to find other weapons laid out around the arena. Now, this meter would allow such elements like impaling and throwing your weapon away more usable. As once your weapon is almost weak, you might as well try to impale or throw it towards your opponent, in case it misses you won't really need it. A weapon should be designed that it cannot kill off a character because it would wear out, giving your opponent a chance, in case you just unleash weapon combos like kenshi's or scorpion's reptitive ones.

The Injury Meter:
The injury meter increases on how you take damage and how much of it.
There are 3 typs of damage that indicate on your meter how much pecentage in the meter you've taken of the particular type of damage. There is the hand to hand damage, there is the weapon damage, and there is the elemental damage.
This meter will let you know how your opponent plays. It lets you see how much of a certain type of attack they've been putting on you. So, it wouldn't be good to keep the injury meter filled with hand to hand. A good fighter would mix and match to confuse your opponent. Also, the injury meter doesn't have its name for nothing. It allows you to activate an injury to the player causing them to fall down for a little while.
The injury works like this: Half hand to hand and half elemental damage would cause your opponent a little injury, while a half weapon and half hand to hand would cause more of an injury, whereas, half weapon and half elemental would cause the most injury. These would surely make gameplay quite complex. For those who wanted MK:dcptn to be somewhat harder than the previous MK:DA.
