Reduce the availability of oGCD's and weaken the power of GCD heals. Increase the rate and potency of Raid-Wide damage from bosses. Make players use their full healing kit regularly.

Remove the focused healing role completely and turn it into a support role based around Haste/Brave/Faith/Shell/Protect/Regen. Provide a full dps rotation to be used while buffs are ticking on players.

Neither option is going to be happy with the decision, but Yoshida put himself on the spot when he catered to Savage players and the spreadsheet playstyle.
