That’s exactly my problem. DB shouldn’t be a game where you need to constantly move all the time. DB is a game where you need to move MOST of the time sure, but not all the time, that is stale and repetitive. Prone (as well as lean and even slide) would add to the diversity of the game. By keeping them out you give players only a limited number of tools to deal with situations.
Right now you only encounter players who are standing, crouching, running or sprinting (let’s forget about jumping and sliding because those two are temporary modes). Four modes of engagement that greatly limits the number of possibilities in a scenario. If players can prone and lean then you greatly add to the possible scenarios in which a game plays out.
Note, this is only an increase in the absolute number of possible scenarios. The average scenarios will still revolve around standing and moving players, the core game remains the same but the essential difference is that the possibilities greatly increase. With a higher range of possibilities players can’t keep on comfortably relying on their opponents constantly doing the same and that’s what I find important in a game.
Not being able to do this doesn’t only make me feel more inhibited, it also means that I’m constantly aware that I know my opponents know that I’m not able to do this. It means that I’m playing without my capacity to be less predictable and that is just downright frustrating because it pretty much is my only edge in multiplayer games.
More elaborate movement and higher fidelity to engage with the surroundings greatly increases the diversity in scenarios in a game and therefore greatly decreases the predictability of the game. This in turn means that matches will be less similar from each other and it keeps the players on edge, and once that happens their brain will keep daydreaming about new tactics even when they’re not playing and once that has happened you’ve got a player hooked.
This is the process that makes tactical shooters so addictive and this is what sucks gamers into its world.
