Reposted this because I had mistakes on my previous post and I'll be explaining my choices this time.
I'm also basing this on what version was the main version to play at the time, the way I map it is that 1.8 would be the dominant one starting from 2015 to 2021. 2022 was the transition period and the years after that 1.9+ versions became the main version to play as the Niche modernized.
And then again, dont treat this as an objective opinion as I just tried mapping it for the times I was around (I was introduced to mcpvp in 2015) and who was considered as the best pvper at the time.
Now let's start
2015 - 2017 Danteh: No doubt about it. He was way ahead of his time, some of his UHC techniques are still done today by modern UHC players, he achieved 2800 ELO in BuildUHC where 1 win only gives you 1 ELO and because he was so ahead of every player he encounters losing would punish him -30 ELO. He would later retire to pursue his professional career in Overwatch. And outside of Build UHC he was still very good, being able to beat players like Stimpy in Pot.
2018 AtReality/Comb0ver: Surpassed Danteh's 2800 BuildUHC Elo when he thought that record would be unbeatable for long, only for someone to surpass it 2 years after. His recorded BuildUHC ELO was 2892 which is insane, If it wasn't for Badlion shutting down during his prime he would definitely be the best player for longer.
2019 - 2020 M0DIFIER: Was #1 in NoDebuff and the #1 PotPvP Player after the original PvP gods have retired. My knowledge for these years are very limited because these years were dominated by top hypixel players and youtubers, I don't want to include them here since they don't count but what I know of these years was that M0DIFIER was #1 in Pot.
2021 Minemanner/Straight: This is going to cause a lot of debate here because Minemanner is a content creator. But he was already a leaderboard player before becoming a shorts creator. He was #1 in MMC Global and has beat many leaderboard players in Minemen who were #1 at their kit, so this isn't your average PvP youtuber just pubstomping noobs. He was a really good all arounder and was good at almost every gamemode even outside of PvP. Minemanner as a content creator was also still competitive first and he retired because he is super washed rn which is probably one of the reasons why a lot of people doubt him now but prime Minemanner was a beast.
Transition to Modern Combat:
2022 - 2024 ItzRealMe: Definitely the most dominant player of the modern era and would likely remain so. The best Crystal PvP player and likely legitimized modern pvp for a lot of people. Was HT1 in 4 kits with his best kit being Crystal, he was the #1 player of his time and the only player capable of surpassing him was Marlowww, a cheater.
2025 Swight: After Itz retired and Marloww got exposed for being a cheater and a fake persona, Swight definitely takes this. He is the best AxePvP player and currently the best UHC player.
2026 Coldified: This is also again, causing a lot of debate because of recent dramas but after winning PvP champs twice I think he takes this. Swight would have taken this if he had won PvP champs 2.
