When I was questing with another druid in MoP Beta, I was able to snap some pictures of old swim form and orca form next to each other. For PvP reasons, people wanted to see how big our killer whale form is. It looks as though the new orca form is actually pretty close in size to the old swim form. My original orca form picture didn’t have any reference objects to be able to get a feel for the size.
Also, we were down most of Saturday due to a hardware issue with our host. At this point, we don’t expect any more downtime related to that issue.
