That's really a damn shame. I've been playing TR single player and I absolutely love it, even with the QTEs which I think it would have been better without.
The multiplayer modes just didn't make any sense, the only thing that would have made sense was perhaps a CoOp campaign with CoOp puzzle solving like that Guardian of Light game. I have absolutely zero desire to run around and shoot at people in Tomb Raider, I'll do that stuff in ARMA 3 Alpha. However solving puzzles and collecting relics with friends? That sounds fun! It's a Tomb Raider game, and they nailed the puzzle platforming this time. I want to RAID TOMBS.
