Which class should I play for completing all the campaign and end-game things?

Hi !. Have been a while since I stop playing GW and i wanna return playing with the reforged patch. I want to play all the campaign and also try to beat the hard mode and also underworld and fow, using one charcter and heroes also, no pretending to farm too much. Would you recommend me any profesion or class? I was thinking about paragon since I have seen in a video that has the best hero comps, but i don't know really if there is any better class to complete all the content, including dungeons and all the things GW has to offer.
