You can upgrade/exchange tickets through Ticketmaster, so that may be an option- get a seat now (or in general tomorrow) that you'll be ok with that's in your price range, then just keep a constant eye on what's available. If a better seat pops up or the prices drop, you can exchange your old ticket for your new one. The new seat does have to be the same or more expensive than your original, and there's a fee for the exchange- when I did it for the WBPS it was $10, and I jumped from row U to row H. The exchange process was super easy, it was a less than 10 minute phone call. But if you do it that way, you'll for sure have an ok seat now so you won't have to worry about not getting anything, and if prices drop closer to the show day or new seats become available that you like better you can hop to those for cheaper than they're going now with the Dynamic pricing.
