Currently the base evasion rating for a monster is always assumed to be one average value depending on the monster level (8388 at enemy level 85), for many monsters and even bosses this value is not accurate, for example Atziri has a base evasion of 12,180 and The Shaper has a base evasion of 11,156. For many builds, especially crit based builds that do not have a significant amount of accuracy, this ends up being a significant DPS loss that is not shown anywhere in Path of Building.
Describe the solution you'd like
A simple way to mitigate this would be to allow manually setting the evasion of the monster in the config, though more involved solutions may be possible and helpful in the future.

Many builds on the poe.ninja ladder are barely (or not even) overcapping their accuracy, such that they achieve 100% hit rate against mobs with this 8388 evasion rating, for example the first CoC build I clicked on on poe.ninja only has an accuracy of 2799. This gives them a decent hit chance of 98%, but if they were to do an atziri they would only really be hitting 89% of the time, equivalent to having a mod with -600~ accuracy on. This is a 10% damage loss for this build, and ~12k base evasion isn't all that uncommon.
For almost every mob in the game poedb reveals that the real base evasion is in the range 8000-8300~, which is multiplied by the monster type multiplier, for example 1.33 for shaper, 1.5 for atziri, this is not consistent, some pinn bosses have a multiplier of 1 and some random act monsters or league monsters have a multiplier of 1.6. I'm not sure how the "average" evasion rating for monsters at certain levels is generated (I think base monster values like this are provided from ggg in the GGPK?) but perhaps it doesn't take into account that multiplier before calculating the average, meaning the chance to hit is misleadingly high. This is just speculation though, I do not know enough about the internals of the GGPK.
Presumably this is the case for other monster stats such as armour as well, though phys damage reduction is easy to manually set in POB currently.
