God please no time travel for the love of Hydaelyn its like the worst thing to do... It suck 90% of the time, bulls*** paradox everywhere, deus ex machina from hell, more plot hole than a godamn cheese and the worst of all "don't touch a flower or you destroy the world... joking go kill half the beast tribe population who care anyway".
Actualy, i'd rather fly/swim in the old area and call it a day than godlike power out of the butt of a uninspired dev.
For the next new area, Garlemald seems logic... but i'd pick another bad guys to confront and put down Garlemald for a long time at the end of stormblood.
ARR = Garlemald ; HW = Dragon ; SB = Garlemald ; XX = other ; XY = Garlemald ...
Yeah... I godamn hate time travel or any time related activity... Its overused and cliche.
