[Besides the story, what am I missing if I don't get the LW packages?]

I played a long time ago in HoT for a month or two, but never really invested much in the game. Now I'm bored at quarentine and want to give it a go again.I will buy PoF but I'm reading a lot of mixed comments about the LW parts that you need to buy with gems.My question is, if I don't care much about the story, what else am I missing if I don't get the other LWs?(I only have the 4th unlocked)

Do I miss stuff like gear, mounts, achievements, skins and other cosmetic related things?

I'm from Brasil and the currency exchange makes everything quite expensive for me, so I would love to know beforehand where to put my money.Any help is appreciated :)
