Whether you like “the ED game” or not is irrelevant, the ED game is here to stay. There will be many qualified applicants who will apply RD and get shut out as the RD admit rates drop to very low levels essentially leaving only those with very desirable attributes to be admitted RD. Those that get shut out will end up at their safety schools. In the end you need to look at previous years admit rates for both ED and RD and see what chance your willing to take based on that and your finances. Personally I would recommend ED to WUSTL to maximize your chances.
