I've had to do some research, checking youtube content creators, dcuo wiki but it seems like the enhanced future warden style was only available for loging in January of this year. Is there any way to get this style currently?
It will probably be added to the Dr Fate vendor at some point. Like the Enhanced Tempus Fuginaut was added to the Dr Fate vendor..... but it took like...... 10 months for the Tempus Fuginaut style to be added?? So it may take a while..... but odds are that the styles from the Daily rewards will end up on the Dr Fate vendor at some point later. Maybe much later??? We shall have to wait and see.
