It is totally true, being left doesn't mean best
Never mind that currently playing doesn't mean more experienced either. Planetside 2 is going to be a new game with new tactics and mechanics. TBH it will play more like HALO or Battlefield 3 than PS1 and my guess is the outfits that stayed in game and oldies coming back (mine included) will quickly find themselves far down the ladder under a whole bunch of super talented FPS Gurus from Battlefield and Halo. Just my prediction. Planetside 1 doesn't really play like a modern FPS with no hit boxes and long kill times, Planetside 2 has hit boxes and fast kill times, totally different thing and the 16 yr old kid that has been doing 8 hours a day on HALO for 5 years will crush us PS1 veterans (myself included)
*just my 2 cents*
TLDR...Short Version: PS2 is not PS1 it is more like HALO/BF3 and as such best now means nothing. Ask once we are a couple months into open beta.
