Yeah it is a great way to catch up as a new player, but it may also he a bit overwhelming, adding to the already steep learning curve.

Alternatively you can also join a multiplayer lobby with for example a friend who has the dlc, you can make full use of their features for the duration as well.

Also, if you end up deciding to permanently buy some, it is always wise to wait for a sale. All but the most recent dlc go on sale multiple times per year.
