Any Cliffnotes of what each class gains in Velious?

[Nastinate]

I played a mage on live during velious and clearly remember being able to throw my pet on the 4 see invis giants at entrance of the arena in Kael run by and coth myself to clear agro. I also remember the coth nerf but from what i recall it was after luclin release or shortly before it. After the nerf, one did have to be about 50-100 feet away from the mob but you could still coth yourself to clear agro.
