There are a lot of very cool animations with different champions. I seem to remember the Legendary ones  most but a few  new epics have some one off moves too :)

The graphic animations and sounds really make the champions unique from each other

I look forward to the new faction coming and what they will look like and sound  like  on the battlefront

When shamrock gets hit he spills beer all over the floor! 

To me, Kymar's looks a lot like John Travolta's in Pulp Fiction. When he's lost looking around holding his jacket

I find the look of lot of champs well designed, Rotos, Siphi, Annie, Arbiter, Valkyrie, Coldheart, among many others. I like Trunda since she has this steely gaze in her blue eyes

I  find  the  stretching  of  Wagonbane's  neck  surprisingly  funny  (the  first  time  at  least.)

I like the body paint and lingerie that most demon spawn champs have amazingly well done. so are the champs in barbabrians, but Julianna looks silly in her snapshot, although she looks great in her full avatar.

okay, here is an absolutely pointless complaint but I've gotta say this somewhere or my head will explode

on her profile, Raglin's poleaxe goes through her cape and it is driving me bonkers

She  also  only  hits  twice,  but  does  three  hits  of  damage  (her  animation)

didn't notice that!
