You are right shooter games have progressed, to what Battlefield is today. That's my view. I compare everything to Battlefield because it really is IMO the one to beat.
If you don't have a story you absolutely must IMO have 32 player battles.
I really don't think BF is at all the best shooter. Having finally played BF3, I have more respect for how they set the game up. I personally HATE vehicles and I rather compare everything to CounterStrike.
But it's like just said below your post, all based on how you play. I personally love the Halo setup of just 4 on 4. I think that's an amazing setup and I feel 32 player battles and larger, you can get lost in the game and your contribution is relatively minor to the outcome of the game. While in Halo, I've put the team on my back countless times in the last 10 kill stretch to win a game.
Edit: It's also you again with the single player side. I haven't loaded up the single player side of a shooter since Halo 1. I couldn't care less about singe player. Also, when you say coordination to kill something, how many people on xbox live aren't using mics? I put a microphone on for BF3 for a day and I ran into 4 other people total that had a headset in use. A LOT of people still don't communicate enough for me to want to play some 32 person shooter online where teamwork is extremely important to bring down vehicles. I've taken down quite a number of tanks easily single handedly though, and other vehicles when I played BF3, but meh, I still usually don't like vehicles.
As for Titanfall being overhyped. That's usually based on how much a person keeps up on gaming. Just like how people hate music because it's overplayed, even if it is a good song, just because it's on the radio. You're subjecting yourself to the advertising and thus not liking it. I don't feel TitanFall is overhyped at all, and that's because I probably haven't seen 5% of the advertisements you have.
