If you were talking about a different game I would totally agree with you. However, there was almost zero story and I don't even think there were really cut scenes. The campaign in the game might as well not even existed. It consisted of regular multiplayer matches with a very brief reasoning for the fight before it began. It didn't even matter if you won or lost the match, you still moved on in the "story". If Titanfall 2 has even 20 minutes of dialogue it will have more of a story than 1, so I definitely don't think it will ruin the game for anyone.
The more I think about Titanfall the more I start to feel like it was almost an awesome Beta game. It lacked a lot of content and I think they will rectify their mistakes in the next offering.
