The total lack of isolation and tension in Dead Space 3 is a much bigger problem than the microtransactions IMHO but I do agree with you that it's an issue. In general EA has mandated that all future games must have microtransactions, seasons pass and multiplayer so that totally changes design aspects for some types of games. Dead Space started off as a quasi action/survival game, leaning more on the former than the latter but nowadays it is an outright bro action game with some light horror elements. It is an extremely conflicted game where you can tell the mandate from high up to sell at least X million units or lose your jobs heavily influenced the end product.
Publishers like EA need to figure out how to make profitable products at all ranges, they have been using the Hollywood model for too long. It's especially annoying because the back office people are often unaffected (HR, marketing, etc) while the actual production and design people get to go jobless.
