I hadn't played a FPS in a long while until I purchased OW.
Because it's PvP it isn't completely repetitive but the maps will seem like it is.
There are some toxic behavior but it varies.
Blizzard has allowed the WoW tokens, which were used for game time, to be used for battle.net balance. Meaning you could farm gold in WoW and buy other blizzard games.
You could earn enough gold to pay for WoW subscription if you wanted to. Though it's be easier at max level with some professions.
