Stop being a shit.
Alternatively, you could generate as much data as you like if you're willing to accept the limitations of a tanking simulator which models healing output as a random variable having some frequency and severity distribution.
Aside from contributing to EH through healing when you're taking a burst of damage, the proc also does have the potential of saving your healer a GCD topping you off to better prepare for an incoming burst. Of course this would only be relevant very, very rarely - but if it saved the healer a GCD every time you took a burst, it would be incredibly overpowered.
I guess what I'm saying is - spell power does affect how your healers heal you in that more spell power means fewer spells they need to top you off. Let's not forget that 300 spell power for some healers is practically an entire tier of content worth of item budget.
Avoidance is almost necessarily better at freeing healer GCDs than spellpower.
Looking at those figures, I can't quite figure out exactly what you did. Which talents/glyphs/multipliers/bonuses/medium size marcupials did you factor in there? Since you are the source of the proc's effect, I'd assume none of the above apply except the ones that generate a buff on your buff bar, but the best base coefficient going is 166% (498) and most of the spells healers actually cast are in the 80%-100% range.
Can someone who has the thing comandeer a healer and work out which if any of their modifiers are applied?
An interesting point regarding the Last Word proc is that disc priests' shields and val'anyr procs directly translate that spellpower into effective health.
Effective health isn't a stat, it's an arguement. In a nutshell, that arguement goes as follows: favor gearing choices which maximize your chance to survive a worst-case-scenario event. Worst-case-scenario events, by definition, never involve anything which only has a chance of helping.
Last I checked, there was a thing called weakened soul that made it so at any given time, your chances of having a priest shield are significantly less than 100%. Therefor, you will not have a priest shield in a worst case scenario event, and it has nothing whatsoever to do with effective health.
The word for what you're describing is "health." Priest shields translate the Last Word proc directly into health. Yes, we know, thank you.
