I’m rapidly coming to the conclusion that it is almost always better to add to HP than defense, for the following reasons:
b[/b] Defense does nothing against damaging status or percent damage effects, while having a higher HP does. 85% of 200 is 170, which is better than 85% of 100 (85, obviously).
b[/b] Defense doesn’t mitigate damage derived from speed, while if you have a huge HP count, you don’t really care.
b[/b] The various “Remove X% of Defense” effects really don’t matter when your Defense is about 10 anyways.
b[/b] Enemy blasting spells are derived from spellpower, which has no relation at all to your creature’s various defenses that I’ve noticed. If you have high max health you can shrug off that Armageddon / Planets / Stasis Sword that much easier.
b[/b] Mend becomes much more effective with high max HP.
b[/b] As rare as they are, the Leak and Pandemonium Drain effects steal percentages of your Defense, and if it’s crappy, then they won’t get anything worthwhile out of it.
Now, I have seen some negatives. Damage-dependent effects like Splash/Thrust/Cleave get better when they hit an health-maxed creature and splash over to a defense-dependent one, but I almost see that as a further argument against focusing on defense. Likewise, the Pandemonium Strike effect does Spider Occultist-style scaling damage off of Chaos Defense, but only the Pandemonium King has that effect.
Really, the only problem I can see that healing spells are much more effective on Defense-maxed creatures than health-maxed ones, because the amount of healing is a static number.
Can anyone check my math on this?
