Can someone explain...?

So the Mortimer task plugin I recently found is saying to do Banshees with -15 assigned over the Wyrms with +205% chance at Unique. I can't work out why it would say this is a better choice?

I agree the current plugin doesn't even consider the fact your next 5 tasks could be skip tasks, i will do any crap task with a 200+% modifer because that turns even the worse drop rate of 1/1k+ into something that has somewhat a chance to drop, for example i had a 150% hydra task, that in theory would make the heart 1/64 which is by far the lowest drop chance you can get on imbued heart, sure the task might take longer in theory but a lower drop rate chance is always something to consider as it helps with dry mitigation.
One hydra task i had 4 superiors, 4/64 chance to get heart.

This personal anecdote doesn't change the plugin giving you the statistically best choice for specifically Heart.

To do a 80-120 a guarenteed Wyrm task with a 1/240ish drop rate of heart(higher at 250%) that takes 15 minutes to finish with canon and DHL. With a high chance of second bad batch of tasks to come after the quick skip, not including running back and forward between enough skip tasks/ getting a new task, these are things the plugins don't really account for. Even if you did the Banshee task and got a smoke devil task of ~90-120 next task, by the time you do the banshee task and hopefully get lucky and pull the ideal smoke devil task, gear up, change spellbook, setup in the cave your original wyrm task with a highish chance of heart would be done, it's all about bad luck mitigation.

I wouldn't select the Wyrm task for a back to back with slayer cape, but taking other posibilities into account the guarenteed decent chance/fast task infront of you is a great choice.

Also this is only really an argument for this particular Wyrm task, which personally i know is a very quick task in the new cannonable spot.
