Installing Battlenet and Blizzard's games

Looking for a guide that helps to install Battlenet, I mostly play WoW, OW, and Diablo. Now I never ran to an issue before with OW and DIablo, but with WoW I have lots of problems installing addons, before I did install all of them with NonSteamLauncher, but using that it was hard to manage the game files. Does anyone have another method? Something simpler so I can run Curse Forge and WoW without this issues? Thanks.
