What is the main area your struggling with? Just the transition from paladin → monk playstyle or just monk gameplay in general? Have you already checked out https://us.forums.blizzard.com/en/wow/t/useful-monk-resources/728548 ?
I could type a bunch of stuff but 99% of it will be irrelevant if we don’t know what applies to your situation.
Windwalker is probably a contender for the most tanky melee DPS right now in PvE and we have a lot of defensive tools in PvP as well.
What exactly did you die to?
Stuns will kill anyone in the current meta so if you get caught without a trinket on any class I think most people understand they’re probably going to die.
