Is this correct? If you're going to use a filler that deals more % of total damage, does it not synergize with a talent that buffs it? To put it in extremes, assuming same amount of globals used for filler and dmg is per global: If mind flay does 1k damage, buffing it with 50% would do nothing for total dps, while if mind spike does 100k damage, buffing it with 50% would be significant increase.
Agreeing on everything else.
