First... the logic is awful.
Second... it's not the same game.
lastly go back a few pages and see our reviews. It's a really solid game, much much more closed infantry game play. The maps are ok, just like any other BF there are good and meh. The gun selection is surprisingly minimum but the way to unlock things is a good upgrade imo. There are fun game modes, I personally like blood money the most. With BFHL it's similar to COD in the sense it's not as team based as other BF games, also very fast paced. I still run in teams, like any other BF it's always better to play that way, ptfo. The vehicle selection, similar to the weapon selection, is minimal due to the maps as well. If you like tanks and such, bf4 is the way to go on that one. Ummmmmmm what else... new dlc, weapons and game play coming tuesday I think... like with BF4 when it dropped it came with dlc months after... BFHL has had much less problems from launch than BF4 did, so connections have been great for me. I haven't had a boot yet nor read of any problems like that.
At the end of the day BF4 and BFHL are both solid games under the BF umbrella. They are different, I would suggest going with BF4 right now just because it's cheaper with more experiences. (Maps, Weapons, Gameplay)... but Hardline is solid and fun.
