I guess Titans would be hard to balance. One-shot from afar by a heavy railgun isn't too much fun in a mode where you (barring a team rez) only get one life per game.
Speaking of team rez, it's the greatest thing. Back in PUBG we used to drop school/Pochinki out of sheer boredom with safe places (run around and loot nothing for 10 minutes, then get caught in a bad spot and get owned without hardly firing a shot). Problem is that in PUBG hotspots, usually only 1-2 guys of the 4 player squad would make it out alive. Options? Either suicide or play it out, with the dead guys then having to wait 10-15 minutes. That shit gets old and boring really fast for everyone. Blackout had the same problem though not quite as slow. Here they give you a chance of bringing back dead team mates (without gear) if you come out on top of a squad fight, and are able to make it to one of the rez stations. This also means you will usually face full squads in fire fights.
Other than that, feels as polished and smooth as Blackops and it's free to play. If they can keep the positive momentum/buzz going with some regular updates, balancing, maps, guns etc. (unlike Blackops which seems designed around not doing a thing until the inevitable full installment in a year), I think it has a lot going for it.
