Scarf joints are an old joining method, allow for the use of smaller pieces of wood, and provide additional strength in this area of the LP. Some top-end builders use them for that reason -- it's not always a budget thing. On your guitar, it's simply a matter of getting what you pay for, and not getting what you don't. An expensive classical or flamenco guitar would have a beautifully symmetrical scarf joint, because while it takes work and care (not a lot, but some) to achieve that result, they buyer is paying for it. Epi generally builds to an excellent standard, and this neck is likely no exception. They're just not charging for meticulous attention to cosmetics on top of proper shape and function. The visible joint is a total non-issue for me, personally, but if it bugs you, return, etc.
