Now that we have new owners, I think it is a good time to propose a rebalancing of plague.
Most uses of plague for strategy reasons include opening targets, increased economy control and the like. At the moment, plague has an indefinite duration and, while curable at a relatively low percentage with Nature's Blessing, that is overpowered.
Plague, at its most basic, is a combination of Chastity, Incite Riots, and a targeted mystic vortex of Minor Protection +Greater Protection (with duration). I have personally had the effect last as long as 24 hrs. I have also cured it instantly on a first cast of nature's blessing. Similarly, I have had perfect Mystic Vortex's that remove only negative spells on a single cast, thus I do not find the Nature's Blessing cures it argument persuasive in terms of balance.
Chastity has a duration max of what I assume to be 7 hours (because with maximum bonuses, that is the longest I have ever seen)
Incite Riots has a duration max of what I assume to be 24 hours (because with maximum bonuses that is the longest I have ever seen)
Taking these in average, the duration should be about 16 hours.
This timing is appealing because that would mean that a plague duration limited to 16 hours would renew upon the next wave of an undead's attack patter. Thus allowing constant plague with renewed cyclical attacks under the normal stance assuming no other speed modifiers.
This is essence is what I propose to balance plague. That plague's maximum duration should be set to 16 ticks. I think plague should further appear as a spell effect in the mystic adviser with a definite counter. Yes, that also means that plague should have a random chance of being "cured" by a mystic vortex in addition to nature's blessing. (I do not find that illogical as plague is a mystic disease nor do I find it unbalanced as few would choose to use mystic vortex to cure when nature's blessing is both cheaper and more targeted, thus this minor change really is just for ease of display and coding of the proposed balance of the plague effect).
Given the natural bounds of the durations of the effects that plague mimics, its current form is overly powerful for a free incidental effect related to an attack, it seems reasonable to provide a definite and averaged duration for the effects that would be in keeping with the attacking cycle and not cause significant deviation from the strategic purposes of plague as currently used in the game.
Thank you for your attention.
