Yeah, but there isnt an option to whitelist certin debuffs that arent ours. Ex: WLD. Warlock wants to have the MS Debuff shown, but only his are being shown. Or he wants to see cyclone. Ect.
The specific spells options take priority over the Show only my buffs/debuffs option. Within each Specific Spell entry is it's own Always Show/Mine Only/Never option.
So if you set PlateBuffs to only show your debuffs, then add Cyclone to your specific spells list (with it set to Always Show), Cyclone will always be shown regardless of the caster.
