I'm going to have to weight in on the pay2win side here. Although you CAN unlock stuff with certs rather than money, that doesn't make it not pay2win. The whole "you're just trading money instead of time" argument is a strawman and a pretty poor one at that.
What it comes down to is that, if you earn 1000 certs and buy an utterly necessary weapon (and there are several of these unless you plan to significantly limit your playstyle), somebody who spent money bought the weapon and spent the 1000 certs on upgrading it (or whatever). So their weapon, passives, health etc. are better than yours. Chances are, with the nice toys, they're probably earning certs faster than you too.
Unless you pay, you simply cannot keep up. That's what it comes down to. It's about as pay2win as it gets and, personally, I'm already seeing falloff in player numbers as the initial spike realises how much they're going to have to spend and/or how little they're going to enjoy the game without paying.
There's a darned good reason that PS1 ran the reserves program. In PS2, unless you pay (and pay regularly - it's only out for a couple of weeks and they've already released several new weapons and upgrades), a f2p player is basically an even more gimped reserve... and the reserves were gimped enough as it was.
/crystalball - I forsee server merges...
On another note, the lack of meta-game is a killer, rendering most actions pretty much pointless. In PS1, the lattice system (which could certainly have been improved) ensured that grabbing and holding bases was meaningful and, by acting strategically you could "own" continents by the simple expedient of taking all the bases and defending the one base that the enemy could attack. It's not exactly a win, but owning all the conts and sanc-locking your enemy was what every faction aspired to.
With the new system, it's actually advantageous to let your enemy have bases, because you can cap them back for a ton of XP and certs. And with nonlockable warpgates on every continent, the entire game is basically an endlessly ongoing game of whack-a-mole with very little to strive towards.
I'll play it. But as it stands, I've got FAR less investment than I had in PS1, so I'll play it less and I certainly won't pay any significant amount into it.
