That is exactly the crap I am talking about. A 1% increase in spell crit means you can cast 1 more free heal per 100 casts in a statistically perfect world, just like 1% parry means you take 1% less damage. Saying that it is a 100% improvement to go from 98% to 99% is spinning numbers and it is misleading. The comparison of how much of a gain it is should come from your empty set (0% mitigation or spell crit), not the point you were previously at. |
. . .
Why not? I used the extreme example to show that at a high spell crit%, 1% marginal spell crit is worth more, compared to 1% marginal spell crit% at a low spell crit %. Is the concept of marginal gains too difficult for you to grasp?
Here, I'll dumb it down for you by showing how spell crit% boosts healing output compared to the "empty set".
0% spell crit, 100% mana cost
X/1.00 = X
This is the baseline. At 0% spell crit, you can cast X heals.
1% spell crit, 99% effective mana cost
X/0.99 = 1.0101 X
marginal gain of .0101 (Not .01!)
2% spell crit, 98% effective mana cost
X/0.98 = 1.0204 X
marginal gain of .0103
3% spell crit, 97%
X/0.97 = 1.0309 X
marginal gain of .0105
5% spell crit, 95%
X/0.95 = 1.0529 X
marginal gain of .0217 for 2% spell crit, or .0108 per 1%.
10%, 90%
X/0.90 = 1.1111 X
marginal gain of .5821 for 5% spell crit, or .0116 per 1%
20%, 80%
X/0.80 = 1.25 X
marginal gain of .1389 for 10% spell crit, or .0139 per 1%.
Note that at 20% spell crit (an attainable level of crit %) you do not gain 20% healing endurance compared to the "empty set". You gain 25%.
ie: If you can cast 100 heals on a given mana pool at 0% spell crit, you can cast 125 heals for the same amount of mana with 20% spell crit. If you're a healer who is trying to figure out how long you can pump out heals, I don't see how that type of information is "misleading" or "spinning numbers".
