Sorry for replying late as well, I was away.
The discussion on this continued for quite the long time while you were gone.
I made some discoveries and realizations in that time.
The primary problem with DoT’s right now, which is responsible for the change to the formula even being suggested (which affects all classes, not just magic), is very strong magics with very strong DoT’s.
These are:
Acid (Same story as magma but slightly (-0.05 base damage multiplier) weaker, smaller size, and better magic speed.)
Metal (Total multiplier nearing 1.3x when bleed procs, which is always. Easy fixes would include making its bleed threshold high, nerfing its bleed, or removing its bleed.)
And, to a lesser extent, earth. (Bleed threshold is a lot more fair here)
Next would be that the new formula makes a lot of mechanics/spells entirely irrelevant if you’re using an intensity build or poison magic.
This includes any charged spell, ultimate move, synergy (as they would only affect impact damage), spell stronger than a blast (in an ideal meta the blast is not the standard strong attack, it should be the standard average damage attack), or difficult to land spell.
This means poison is now all about finding the largest, hardest to avoid attack and then spamming it while running away. You don’t need a further game plan or to be fun to play against.
My bleed and plasma synergies being entirely pointless is really disparaging.
Oh and blocking also becomes entirely pointless against intensity builds, as damage of the hit, is, again, irrelevant.
This big ol chunk of text is entirely for mages, I don’t even know how it would affect weapons or strength builds. If it’s already a nerf for pure magic I can’t imagine it being a buff for the other things that use damaging status’.
Oh and as an aside, look into how crystal interacts with ultimate moves. Apparently ultimate moves apply stackable status’ twice per hit, which can make crystal (0.975 damage multi) apply it’s crystal shatter damage bonus multiple times for humongous bonus damage in a massive area.
Going to post this so I can get involved in the current discussion about vit without forgetting.
