i personally didn't this time around. the x2 xp is worthless as it doesn't take long to level up now at all. i'll be a shit bucket colonel without playing with any x2 xp, just using the occasional 100 and 200 xp boosts from Battlepacks.
the 12 free Battlepacks i find worthless as well as i never get anything for any gun i use from Gold Battlepacks.
as far as weapons go, i don't even use them. they aren't allowed in competitive play so i don't want to get into a situation where i only use a DLC gun. i unlocked all the guns from Second Assault and i never even use them. the MTAR is still a bit OP though so if you like having an advantage over others i guess its not a bad option.
its nice to have new maps but again they don't run DLC maps in competitive so i don't need them.
for me, premium and DLC is worthless this time around.
