I'd like to add a little "hack" to know if a given boss will/won't have an animation on it's Podium:
If it is a cooldown boss, therefore if it appears on the "Boss Cooldown Window", his podium will be like shown in his cooldown timer. If you can see an animation on the Cooldown Window, then the Podium will also have the same animation. Just a little trick, so you don't have to check a list everytime. Only works on bosses shown on the cooldown list, tho, thats the downside :)
