Basically, I agree with Stahlhelmii's comments: this is a game with realistic ambitions, so complaining about one-shot deaths doesn't quite fit with the game itself. Nevertheless, I agree with one thing you've said:
Every time I drop into a far objective and find out I have 2 people with me I am just perplexed, where is my team? I bring up the scoreboard and surely enough, there's 32 players on my team. But where they are? Somewhere in a high window waiting to pick off an enemy or two probably.
it is quite frustrating to play on servers where the majority of players are racking up kills but not contributing to the overall territory gameplay (based upon team-points/kill ratio). I played Fallen-Fighters on a server today and I swear only 7 of the 16 players on my team made any attempt to capture the Central and East parks as Axis. What's even more worrying, we won both rounds of the match easily, all the Allied players refused to stray beyond the safety of their spawn point. I expect that eventually players will realise the importance of actively heading into capzones and gameplay will improve: I'm a novice to RO and for the first week or so of the Beta, I will admit I spent most of my time as a rifleman trying to pick off enemies from a distance, until I realised that it is more lucrative both on a personal level and for the team to try and capture objectives and to hunt enemies in and from those same objectives.
Finally, I also agree with what a few people have said in that the pace will not accelerate with time, I think it will decelerate, as players become more au fait with the maps and the nuances of their weapons.
