Larian Studios Forums Baldur's Gate III Baldur's Gate III - Suggestions & Feedback Why I Want More D&D 5e Rules

i thoroughly enjoyed pathfinder 1st ed. heard pathfinder 2nd ed. was quite a nerf which i personally dislike. new to dnd5e. does level 20 brings to high level fights? are there mythic progression in d&d5e? or it's simply a nerf version for low level campaign?
