However, since the game is fresh for you, I'm not sure you would appreciate that variety until you have a few games under your belt.
This is an excellent point, you really don't need any of them.. particularly at first.
Once you played a bit, the quest and loot packs are quite good.
If you want more map variation get the map and new battlegrounds ones.
Personally I think the dead one is not so great, and the sov once whatever it is called a bit of a waste of money.
And checkout some mods, if you want more loot variation try the Black Market Bazaar:
