No, they don't. I'm sure some of the fixes they've made help PVP, but they also just help the game in general. What fixes did you see they specifically pointed to PVP as to why they fixed it? I'll wait. You are delusional.
For who, though? Not everyone enjoys the scenarios Roland mentioned some posts up. I've never been a fan on PVP in games like this where you can lose hours of work when you're not even online to defend it. Felt the same way when I played ARK a bunch. There was no way I'd play on a PVP server where dinos that took literal hours to tame could be gone in an instant. If that's "content" to you, cool. But it isn't to me and I don't want TFP to spend any time on that as it doesn't benefit me at all. And as much as Grandpa Minion likes to make up stats, I'd bet PVPers are quite the minority in this game, so why would TFP cater to them? Just give me bandits, more quests, and if time permits other new stuff like the raft, helicopter, or new biomes. Anything that adds to game I play, which anything PVP-oriented would not do.
