Since the franchise is on sale right now (and because I want to maximize my "bang to buck" ratio), I'm considering buying the franchise from the US store and gifting it to my EU account instead of buying it straight from the EU store.
Is such a thing possible and, if so, does it violate Blizzard's terms of service?
In addition, will there be any gameplay perks due to e.g. regional restrictions? I've read about Global play, but I'd rather make sure that no subtle issues pop up.
