Calling it right now.
Corehound mount is going to be the new asshole mount people get on to stand on top of and block NPCs from being interacted with. It is just too huge.
Also to people worried about it being hard, it is LFR. You kidding me? A group of tools with no clue could clear it thanks to determination. You can assemble as many friends and guildies as you can and just carry all the fails to victory quickly and easily just like you would any other LFR that you actually had a guild presence in. You think the other people mean anything at all in a LFR right now if you have like 8 guildies in it all doing over 400k dps? No. They dont.
