I'm more on the side of disagreeing with you, but for anyone who wants reference, I was a heavy GRAW player.
I used to do LOTS of clan matches in GRAW1/2 and I can tell you that the multiplayer was extremely tactical, at least siege mode was. It was 100% teamwork based and you would get completely owned if you didn't work together. Bringing that into GR:FS, I personally love the game for what it is, but this isn't just Ghost Recon.
Future Solider is essentially a combination of Gears of War, Call of Duty, and Ghost Recon all in one. A couple matches and you'll know exactly what I mean for the most part. With only four modes, some of them are highly more tactical than others, but the biggest problem with this game so far is rushers. People just don't understand how to work as a team, don't use mics, and just run at objectives or enemy players like mad men. I'm hoping this fades away, as a lot of the people I've talked to are CoD players wanting a new game to play... but the game feels so different because of map size.
These maps are just tiny, plain and simple. To the point that they really only work in Conflict mode (which is a mode based on capturing different objectives and holding them down). The fast paced gameplay works incredibly well here, but once you hit the other modes the game's weaknesses show a bit more.
Siege is a mess. It's my preferred mode anyways, but they made some stupid design choices. For one, the base is always right in the middle of the map and the attacking team spawns are random (generally two or three different spots). What ends up happening is that the defenders have a bonus 10 seconds to get positioned, but since the spawns are so close to each other, it really turns into getting killed about 10 seconds into the match. If you've ever played Siege on a Ghost Recon game, this is a joke.
With a full team it is slightly better, but the nature of small maps and only 6v6 is kind of embarrassing. Especially when your previous games held higher player counts.
Even with the negative tone, I'm having a ton of fun with the game. I want bigger maps, though, that's for sure. I personally think that if their were bigger maps a lot of the complaints would end from hardcore GRAW players... but oh well. It is what it is. Worth my money, at aleast.
