I never do savage/X stuff ... i only did the poneys during HW and the HW birds during SB ....and Alex1S for the HW relic .
Some things in this game are unnecessarily difficult , like the Stormblood quest ( shinryu ) or the 4.3 primal , in fact even 1 year after you are almost sure to fail the first try if you have Susano in the trial roulette ....

But these threads have to stop , the burn IS NOT hard at all ... it has the same difficulty than Aurum Vale / The Vault , and the mog dungeon in HW -i forgot the name .
Even the previous expert roulette , with The Swallow's Compass was harder than this one , during 4.3 i got my tomestones in Eureka / Hunts / HoH to don't have to bother with it .
