State of game for going for 100% completion

[TeddyTheCat123 6]

I want to 100% this game as I used to play it a lot on an old account but how is the game now for 100%. Is the dlc easy? How hard are the trophies (grinding isn’t a problem) do I need to boost this game? Is dlc popular? I really want this game but am unsure how easy is the 100% I have a boosting partner but is 2 players enough?

From what I remember:

-  There were a couple of servers that were still full but that was almost 2 years ago. 

- You need 4 to start a server. 

- Unless you had the DLC weapons unlocked on your old account and can self boost by dying and picking up the weapons with your new account (or someone that are willing to boost you,) then you'll have to unlock their respective assignments to unlock it.

got 100% about 2 months ago, everything can be done with 4 people boosting if you rent a server, you can get most gun kills playing gun master and scavenger.
