Is your feature request related to a problem?

When PoB calculated weight of mods, some mods get drastically overweighted while in reality they are useless. As example, mod like "Cast speed %" for "cast when Stun" build somehow get weight of 81 while "increased Fire Damage" get less than 1. Another common offender is anything that give culling strike.

Describe the solution you'd like

Add ability to in addition to "find best" - manually review weighted mods, remove them from weights and "rerun calculations". It especially useful in cases like searching for "Megalomaniac" with amount of possible nodes being to high for single tradesearch. (It also and be added option to make some mods mandatory)

Describe alternatives you've considered

Making some manual list of "commonly overweighted mods" like Culling Strike, "you have culling strike against cursed enemies", "Elemental Overload" etc.

Additional context

No response

The issue names no files or tests; start by locating the existing weight-calculation and “find best” flows in Path of Building. Define how users would review and remove weighted mods, rerun calculations, and optionally mark mods as mandatory, then verify those workflows with the Megalomaniac and cited overweighted-mod cases.
