The lack of voice chat is a bit disappointing, but being a Battlefield & Call of Duty player for years, I know it's not necessary at all. I've used voice chat in BF4 maybe a handful of times, but mostly no one uses it. It is fun with friends, though. So, I guess, in that area it'll be missed.
The lack of bots and waiting for a full match means nothing to me. Battlefield and Call of Duty are pretty similar. They have larger lobbies, but the game won't start until a certain number of a players have joined. In Call of Duty, you're mostly staring at the lobby screen while you wait, but in Battlefield you're allowed to run around the map with the other players until the actual game starts. I'm hoping it's more like the latter, where there's something to do while you wait. Neither of the games have bots for multiplayer, either. That seems pretty antiquated, now that I think about it. The only recent game I can recall having a CPU player in online multiplayer would be Mario Kart 8, and that's only if a player drops mid-match.
