UHC tiers in crossplay currently have the highest standards UHC has ever had. I am a LT3 who ranks superior to everyone else and am currently the 2nd best(just behind Obsisity, a HT3.)
There is currently no one above LT2+ since its very hard but it is achievable. You should start playing crossplay and prove superior!
Crossplay is basically Java + Bedrock compatable which just means Java pvp.
