You cleared with nearly 5 minutes left. I would definitely say you could push it higher. Getting the pylon right at the end was pretty lucky.

I am not against mixed teams if you can manage to play them well and they mesh together. Crusaders are probably one of the safer classes to mix with a Tiki doc because they are pretty sturdy and can still stand in lightning affixes better than other classes. I just don't like playing mixed as muc, because I like to keep my teams as simple to play as possible.

I think Deville's argument is that adding a zdps usually isn't a big of a gain as people think. You would in a lot of cases get better overall damage and clear speed if you just focused on 4 dps classes assuming you can find a way to make them able to survive higher difficulties.

Tiki doc is great to add in to other teams because they provide the ability to prevent elite affixes and provide some damage buff while they do so (really good ones at the like BBV Slam Dance). They just don't work in all teams. Trying to run a tiki doc with WW barbs for example would probably be in exercise in frustration due to the desync that would cause. Or running a Tiki with DH's. The DH's are still so squishy even with the tiki support that they just can't hang in melee like your Sader/WD comp can.
