Seems the movement in the Beta was meant to attract COD players
Let me start by saying that there is nothing wrong with a developer trying to attract players from their direct competition, in fact, that's what every business needs to do. but to go to the lengths as to change the core of a franchise is going a tad overboard in my opinion.
I am sure a lot of people reading this has seen the reddit post by now titled "This movement should not be possible in BF6 DICE, needs to be addressed" it has almost 30K likes. After seeing the video clip attached in it I was shocked. The player in the video was bunny hopping all over the place like a Mexican jumping bean, jumping out of windows like being shot out of a cannon, high into the air. It was ridiculous to say the least. This type of movement needs to stay in COD. DICE, you need to address this in some manor, like for example, add a fatigue meter, or something to that effect, so this type of movement can't used or abused. Should only be able to jump up while running once every few seconds. not chain jumping like what was seen in that video.
Now about the slide. I like the slide, it can get you out of trouble. But the slide is a little too long. shouldn't be able to slide 10 to 20 feet unless you are going down a hill. to slide that long on a flat surface is, yet again, too ridiculous. The sprint and springing with the knife equipped is fine. its been faster in prior Battlefield games. just the sliding and especially the jumping needs to be toned down.
