You’re getting the “standard” edition of the game. Sure, you’re not getting the expansion packs or other cosmetics, but neither is any other person that doesn’t buy the deluxe editions.
No, what they usually give you is actual customization options because in the full-priced standard edition those do not exist anymore.
As character customization has by now been apparently redefined as being wholesale "cosmetic" and thus locked behind an deluxe version up sale, MTX spending and FOMO season pass grinding.
It's a sorry state for AAA and increasingly even mid-tier developed games.
Often enough it directly affects gameplay, instead of playing with/against individual other people, which in many games used to be recognizable by their character customization choices, too often multiplayer now ends up looking like the clone wars.
As the only people that stick out with their customization are those that spend money on having any choice other but the one default choice.
