1.) Ps4 Feels like 60 FPS in instances, less in open worlds, but overall very smooth

2.) War > Pally (Jk,) You could level to 50 in a day or two if you seriously go at it (use the DD or AV first room method for quick levels)

3.) Once your 50, I suggest spamming dungeons to acquire i70 gear, while earning the myth to buy i90. Then once you feel ready, head into coil and earn more i90. I would steer clear of CT, no use getting i80 when i90 is faster and better.

4.) It's not clear yet whether its thief or ninja, but more than likely one of them. Also, a gun class is coming, but they said it isn't what we think it is,

Hope this helps~
