A lot of players may be wondering what groundstriking is and why it's a problem. Groundstriking is a method by which you can shorten the time it takes for you to be able to activate your block in certain scenarios. You can perform the groundstriking maneuver in situations where you realise you're going to miss your attack.
Picture this: You attempt to slash your opponent, and because you misinterpreted the range, it misses. The expected outcome here is that your opponent will have an advantage because you made a miscalculation. Your opponent should have already attempted to match your swing to perform a counter, likely going into a feint to close the distance between you. Because you missed your swing, you're going to get hit. That is how it should be. You made a mistake, and you should be rightly punished for it.
However, by utilising groundstriking in this scenario, you're able to completely reset the balance of the fight, because instead of going through with missing your swing, you angle your slash downward in order to hit the ground. This allows you to block almost instantly after hitting the ground, which means instead of taking damage, you may even have a chance at launching a counter on the counter feint attack that your opponent was already launching at you.
For a lot of the playerbase, "groundstriking" is not something that is commonly spoken about, simply because it has no real bearing on whether they will succeed or fail in a game.
However, in the duel community, groundstriking is something that can easily turn a losing situation into a winning one.
I'm not against groundstriking as a mechanic. I think it's fair enough that there's a shorter recovery time if you hit something versus following completely through with the attack. However, it is exceedingly clear that it is in need of change. I think it would have an extremely positive impact if the time it took between hitting the ground and being able to block was increased, because right now, it's effectively instantaneous.
