Coming back from a 7 month vacation and i find myself asking this question.

Wyre, you scrub. Welcome Back.

Here is the current OP/not OP meta:

Scouts are not as OP as they were (especially cloaked scouts) but SG/RE is still OP.
Assaults are more OP than they were and replaced many scouts on the field.
HMG is still OP.
Commandos are very much more OP.
Swarms are OP but vehicles are still annoying.
Redline snipers are still pussies and still OP.
Strafing is OP especially for scouts and Min Assaults.
CR, RR, ARR, ScR and TacAR are all OP.
Laser rifle is OP at range but still terrible close/mid range.
Bolt pistol, smg, Breach SCP are still OP.
Plasma cannon is not OP but much better than they were. Prepare to die to them.

Tryhards still proto squad stomp.
Blue berries still suck.
Match making is still awful.
You will very quickly get tired of the train yard map as it will be every other game.
CCP still can't code properly as many bugs and glitches still exist.
And last but not least lag, lag, lag, framerate drop, lag.

So yeah, welcome back to hell.
