Decide Whether to Buy DLC Based on Your Actual Playtime So Far

The DLC is on sale, you have already sunk a fair few hours into the base game, and it is genuinely unclear whether you will actually play it or just own it. This weighs what the DLC adds against how you have actually been playing and gives you a direct buy, wait or skip.

I have played {BASE_GAME} for roughly {HOURS_PLAYED} hours and I am deciding whether to buy the DLC. Based on what the DLC adds and how I have been playing so far, give me a direct recommendation: buy now, wait for a sale, or skip entirely. Explain the reasoning in two or three sentences, not a full review.
