Basically what they are saying when they say it's not a true fps is really "it's not a CoD clone" or "It's not an Arcade Shooter". Which IMO is great because those types of shooters are terrible. Flashy....but terrible.

Please elaborate.

He is not wrong, he has an opinion. Unless having the brain capacity to generate free thinking is a crime, he is not wrong. I agree with him that arcade style shooters get very stale, very fast.

Oh I see what you're saying. And in that case, he is quite right. I have seen several posts that say "nerf vehicles, this is an FPS not a tank game" or "lets see more small areas where you can't get vehicles, they shouldn't be the focus of an FPS" or "lets get rid of vehicles, they don't belong in an FPS". And, what is the most popular FPS right now that doesn't offer vehicle warfare..? You guessed it, CoD.

You're wrong in your assumptions.
If you're not enjoying yourself now, that's alright. We're at a phase of the beta where vehicle spam is the goal. There is a reason every single noob can get on the battlefield with a tank. The devs are testing vehicle balances.
Later on two things will happen. The first is that vehicles will go back to being what they're supposed to be. A support element for the team and not a personal giant cannon.
The second thing that'll happen is that the entire Dust world in general and the maps in particular will get much much larger. In maps of that large scale you can't really cry "Enough with the vehicles, they are ruining the game!" because they are not. They are a part of the military engagement and will slowly fall into their rightful roles in the battlefield as commanders learn to unilize them properly.

So this is a true FPS. It's just truer than most people realise a FPS is supposed to be - a full blown military simulator.

Kill streaks in CoD are not "Vehicle Warfare". They are... a game wrecking mechanism in my opinion. Kill streaks promote giving players an unfair advantage. If you are good, then you can win a FFA Deathmatch no problem. But if you aren't the best player in the game, and you just happen to be avoiding the best player, you may rack up enough kills for that chopper gunner. Now, you get to spam the map with an insta-kill for 30 seconds, and that player that was going to beat you, now has no chance because you just knocked your score up by 15 kills in 30 seconds. Suddenly, that game has been ruined for everyone that actually out classes you.

Lol. El... Oh.... El... You can spawn free vehicles right now because they are stress testing vehicle warfare. That isn't going to be a part of the final game. It isn't even a game breaking mechanism. Somebody spawns a militia tank, gets somebody in the rocket turret. *BAM* I'm dead, 15,000 ISK Assault suit down the drain... So, I spawn with a forge gun. *BOOM* Vehicle damage +25. *BOOM* Vehicle Destruction +100, Kill +50, Kill +50. I think that should cover my assault suit. If anything, you should be happy people can spawn infinite vehicles right now, stock up on those 100,000 SP vehicle killing games while you can.

You're saying that because you're a Call of Duty player(not sure if fanboy though)

Just because vehicle play is not allowed in a lot of FPS games, it doesn't necessarily mean they don't belong in them. Do I get irritated when someone driving a tank with a good fit runs the map and doesn't die? Hell yes. Do I think CCP should remove vehicles from maps or nerf them? Hell no. Vehicle combat was always going to be an integral part of Dust, this is combat on a planetary scale, not just a little sector of a city. I have played other FPS games and finally someone got it right.
