At FanFest 2014 the trial roulette was called the "Extreme Primal Challenge Roulette" and included IEX, GEX, TEX, etc.

This year it's been re-titled the 'Trial Roulette' but it's unclear if these will still be the EX trials.

Is there a mod who can answer if the event will still be EX fights? Or whether the trials will be comprehensive or only the 3.x trials? Any help would be appreciated!
