You are correct, buying the DLC ruins your matchmaking permanently. Complete waste of money.
Every game loses it's value after a year or 2, in this case closer to 3. Offering a game for free seems like a nice gesture, but then presenting an 'offer' at half price seems appealing, but really that's the main sale. The bait was to offer the game for free because nobody would pay £17.50 for it. To be honest, on their end - it's a good marketing ploy, but some of us are smarter than that! (cheeky)
That's why the community should vote with their wallets. They will soon change their tune.
Agreed, R6S has absolutely nailed it to be fair. I've not bought a season pass on there, but having the content release as it does it just the perfect balance. The game is clearly well-supported as it's being supported continuously. It's a shame Activision have made it so that with BLOPS 4, you can either have the season pass or not. I get that it causes less fragmentation of the userbase, but it's also scummy and forcing players into a total shell out of around £90 for the actual full game experience, when they could adopt the system that nearly EVERY other developer out there is pushing.
I tried playing this last night, loaded up the campaign and it threw me back into an old saved game from when I owned the disc years ago. I just couldn't play it. Far too much going on, I wasn't even that far into the game but I kept dying over and over and I was only playing on regular ffs! Needless to say I'll be going nowhere near online :S In the words of Murtaugh, I'm too old for this sh*t XD
