As long as this community prefers to use DF the way they do - as well as the nature of DF itself - attempting to marry it with high-level team coordinated content will never work. Unless you alter said content drastically, which leads to Alexander Normal Mode. Expecting that element to succeed with Savage, on launch, where things like team composition alone (an element DF doesn't account for, as it just throws whoever, as long as it's a tank/dps/healer) is a factor on success is simply naive. When DF, for example, can throw you in a party with 3 BRDs and a MCH as your DPS, along with 2 ASTs and 2 PLDs, no sensible person is going to bother sticking around. In VA such a comp wouldn't make a difference because the bar is pretty low there, but it wouldn't fly in much difficult content.

A more sensible suggestion would be to implement a cross-server PF feature. In fact this is something Yoshi himself said he wants to do, so you should push for that.
