Blizzard should remove WOD Pathfinder or at least get rid of reputation requirements

I am quite new to WOW and I found that passing old expansion like WOD without flying really frustrating.I am currently in BFA with Ilevl of around 420 and I enjoy doing dungeons especially M+. I also want to try other classes and factions,but I am quite afraid of doing boring quests again and again without flying in old expansion areas. It is really disappointing for the new player like me . Pathfinder is not a problem for the current expansion BFA as I can fulfill while enjoying.
