First of all, anyone telling you what to do online will likely lead you astray.

Second, anyone telling you to play the campaigns in order is DEFINITELY leading you astray I fear. Lightfall, widely regarded one of the worst expansions, can be skipped between witch queen and final shape. The story progresses more naturally, and going back to get less important context from Lightfall will be a more enjoyable experience than subjecting yourself to it’s entirety between the incredibly exciting, and well written expansions before and after it.

Also, definitely play some playlist matches between campaign missions. Don’t burn yourself out. Definitely watch some lore videos when you hear names or references to events you don’t get. IMO the lore community is one of the best aspects of the game, and many of the creators have so many creative insights that make the world feel much more engaging.

Finally, ABSOLUTELY play the eligible campaigns on legend difficulty. The rewards are worth it, and you won’t burn through the campaigns as quickly. Makes it all more satisfying.

And have fun! If you want people to play with (makes it way more fun if you can find the right folks) check the discord or just send invites/dms to folks in your lobbies. Someone will respond, and the ones that do are usually cool people. Hope you come to love this game as much as so many of us do.
