Furthermore, if you forgo the ignite and rely on the grievous wounds debuff and fail to get the kill, then it is simply another example of Ignite > morellonomicon.
The point is that morellonomicon is underpowered and has lost viability. It was added as an option for casters to augment their arsenal for the heavy sustain champions seeing that attack damage champions had executioners calling. It has since been rendered useless in this regard as you must first bring a high sustain champion to below 40% to trigger grievous wounds. I shall repost later with math proving that I am right.
I'm hoping that your next post will clarify this one, and look forward to the math stats to back up your claims. I'm particularly curious about these "MANY BETTER ITEMS" for the niche situation at hand.
I imagine you're assuming a champion with considerable sustain, who is also not tanky, as you seem to be discussing an opponent who would fall to burst, but for their sustain (even perhaps a health pot).
As far as critical build on burst casters goes (since you're a priori ignoring non-burst casters), that would be boots, deathcap, and later on a Void staff. The rest is AP, AP, and more AP, unless the situation calls for something else. The 3 best flat AP items for a mana-using champion are Archangel's Staff, Deathfire Grasp, and Zhonya's Hourglass. Since a burst caster doesn't really care about CDR or mana regen (damage first and foremost), that means that either DFG or ZHG will have to take the cut. Since DFG also amplifies your whole burst by 20%, I'd say that's the one you keep, unless you really need that invulnerability for some reason. Thus, the simple question is whether 25 less AP is worth the ability to automatically prevent your target from healing or being saved.
An interesting question: does a burst caster ever really need to worry about sustain and/or regeneration? The longest burst that's still considered a burst lasts about 3-4 seconds. The best regen I've seen on a non-tanky champion is < 45 per 5; which means your target has an effective 60 more hp (less than) that you need to consider. By that token, why is Ignite, a DoT, so often considered a burst-caster "must"? As opposed to a spec'd Exhaust? Or Teleport?
I guess the end question is whether the extra 25 AP + the true damage DoT from Ignite is required on burst casters, or whether there are other options for burst casters that might let them be better overall (e.g. Clarity, Teleport, or Exhaust).
I think this perceived "need" for Grievous wounds on burst-casters is misplaced. It's much more effective over the long term, on more traditional 'laners'. That is, Karthus would make much better use of this item than LeBlanc. Once he gets his target below 40%, they can never heal back unless they get out of lane (the effect has no cooldown, so Karth's pings re-proc the effect every second or so). Vlad would actually love the item too, if it weren't for the mana regen that it wastes on him.
Anyway, I look forward to your follow-up.
