Well , I wouldn ' t consider it an upgrade , but no , there is no way , you will need to wipe your computer . <| sep |> Pallys are great and generally better but have no instant heals or hots so struggle in a lot of cases e . g . suppression room . Priest is super useful in Naxx with shackle for Heigan and trash and PWS being mandatory for some encounters like Maexxna . Also Dwarf Priests have Fear Ward which is super helpful for noob tanks and makes some fights easy mode . Don ' t get me wrong , Pallys are WAY better , but Priests have their uses . <| sep |> Annoys me too . I had to double check to see if that ' s how it was actually spelled . I think someone was trying to be clever and failed . <| sep |> Campaign is best since Modern Warfare , but still a shooting gallery full of idiot enemies . The set pieces are really nice though , and the story and characters are great for an action movieish game . Multiplayer is hot garbage . Go for Titanfall 2 or Battlefield 1 if that ' s you main interest , and just rent CODIW on Redbox . Remastered doesn ' t hold up , sadly . We ' ve made a lot of progress in gaming since it came out , and the nostalgia wears off very quickly .
