PVP is what I started off playing in Minecraft, mainly because I found it fun, and all my other old friends used to play it. I started out on another server playing UHC, which then I switched over to a Capture the point type gamemode (Similar to Domination from Call of Duty). This is where I met a lot of my friends, this competitive PVP phase lasted from 2016, all the way to the end of 2018, where I quit due to lack of enthusiasm towards the gamemode itself.
PVP in general is fun, sure it can be frustrating at times, but I use it as a hobby to take the edge off if I'm bored of jumping on parkour or just chilling around and want something to do. It's a good thing to pass the time and enjoyable if you're into that sort of stuff haha.
