Better Rewards for Ultimate Bahamut - Next Tier Gear
If Savage was designed and mostly completed in 320 gear to have a chance at 340 gear, but Ultimate was designed and must be completed in 340 gear.
That person who completes an event that is purposely designed to be harder, should be rewarded with something better for the time invested on something locked behind Last boss of 320 designed content, that is fair.
Give Hardcore players some future proof reward, or early access to something other than 1 more materia slot that may or may not increases your % chance by .5%. Say early access to Relic Weapon/Skip Relic-Step with a Key Item obtained from Ultimate, or Relic Gear that you can customize with Penta-meld slots with additional iLvl.
This is the golden opportunity to fix, add onto the way things are now, cause the formula hasn't changed at all since inclusion of 24-man raids.
In other games not only once did i ever get upset at other players getting better equipment, if it meant they worked harder and dedicated the time for it.
If done properly, It wouldn't affect how fights are designed for next savage raid, since Ultimate will be part of the formula that you can't skip last boss of Savage.
