I personally am not too keen on the endless wave thing. I think the 10 rounds is enough for one game. I guess they could provide the option for people who do want it though. But you do kinda get that in backyard battle ground.
Yes, but with the 10 waves, on hard, My team almost always still has the garden/graveyard health meter at 90+%, and on Craaaazy! it differs but usually it's over 50%. Essentially, in Ops, you don't even have to guard the garden/graveyard because by the time you'd have to worry about it getting low on health, the game would be completed anyway. If there was an endless mode, every little swipe from every zombie would actually add up to mean something. That's just my thoughts on it, at least.
