I bought BfA but I only managed to play a month into it or so. I think I maybe hit 119 on my main then quit because of life/the game didn't feel like my cup of tea. I am hyped for Shadowlands but my friends that play the game have all quit BfA. I've been told that the gearing is awful and that lack of corruptions/essences make the game unplayable as a new 120.
I mostly collect mounts and I would like to get back to that before SL drops so I don't have to come back to the old stuff while progressing on new stuff. I also don't know what will happen to Assaults/Warfronts that might make it super annoying or hard to get in the next expac so I might want to do them now.
I don't think I will set foot in any end game content and really only need enough gear to feasibly solo Legion raids/hold my own in world content. Don't have flying either which will suck. Is it really that shitty to come back if all I will do is rep grind and hunt for collectibles like mounts/pets?
