Currently there is no way to set attack of opportunity and such things as reactions that can be prompted or "asked" for right? I SERIOUSLY hope this will change so all reactions can be included in their reaction system.
My suspicion is yes. The EA version is probably only applying to a limited number of options so that we can test out how well the system works. Full release will then probably have a far more refined version of the mechanic, applied to everything that should be covered by it.
