They can't even maintain internal consistency for the main reaction they have - Sometimes they call it by its correct name "Opportunity Attack", and sometimes they call it by the name that was used in earlier editions but is not correct in 5e - "Attack of opportunity", and it flip-flops back and forth depending on where you look. This may not seem like a big thing, but it's hard to have faith in a company doing right by a ruleset in their adaptation of it, if they cannot even maintain internal consistency with the terms of reference they use.
It's EA. They'll still clean all this stuff up. I'm sure.
