Hi there and welcome to the Forums,
I personally don’t think PvP is for CubeCraft Bedrock. In Bedrock, we have to remember that there are people playing on lots of different devices, with some of them not being as good as another. Where as in Java, everyone plays on PC, so everyone plays equally. However, the closest you will get to PvP on CubeCraft Bedrock is Survival Games. I also don’t see why you can’t PvP your friends in your own world (I would recommend one if CubeCraft’s Survival spawns from the Marketplace, e.g. Candy Kingdom). CubeCraft have also mentioned that they are in the process of transferring some of their games from Java Edition to Bedrock Edition, and employed a few new developers to speed up the transfer, so you might be in luck (might).
Thanks for your suggestion anyways. :)
