A1 savage is a dps check
A2 savage is a dps check
A3 savage some mechanics still a dps check
A4 savage who knows no one has beaten it. (safe bet is its a dps check)

The current endgame content is definitely a dps check.

That being said, it would be cool to see some customization at least in the way of cosmetic. I would like to be able to add fire or a green poison effect to all my attacks.
