The crazy part about WoW for me personally is that the usage of the PTR to test expansions and patches using gamers. It's essentially free labor by WOW Classic TBC Gold players. But how frequently do the devs actually take the critiques given to them? I am aware that Torghast in the alpha was very popular among pretty much ever WoW content founder I followed. Yet they rather carved out most of the interesting bits, forced players to undergo it for yet another currency, and then had to return and nerf it because they had added in random affixes which were very unpopular.
SWTOR nowadays is pretty damned good because they changed it up and left it just doing the story missions about the planets was enough, and the stories are great, though some expansions are certainly better than others.
If you would like to experience a game that has a fantastic story you can casual for your hearth's content without losing the simple MMORPG mechanisms (I personally think ESO lacks), I advise you try FFXIV. Best of all, unlike WoW, FFXIV retains all dungeons and raids level synced and contains them on a roulette, meaning you can always find players to conduct them more or less how they were at launching.
Personal stories make me want to play all the races and have fun together, get to know their stories. I will willy-nilly across the map and there's a pursuit and someone to talk to everywhere. I realised I adored GW2 when a caravan pursuit was about to begin and a priest came out and cheap WOW TBC Gold gave a speech, blessing the trip and the caravan NPC was commenting under their breath
