Allow Players to Use Fred to remove an entire line of feats that require prerequisites like when a feat is removed by the developers. The current is too tedious, time consuming , and punitive to someone that decides a character is just not viable but was 90% built correctly but the mechanics for a specific feat line are just not comparable. This traps WAY too Many newer players into a build at upper heroics and low epics that they just give up instead of begging others to nurse them through getting TR Tokens of twelve or having to run old quests at EN for 33 token fragments.
The most obvious example would be a player decides that it would be cool to make a two weapon dwarven axe (or any two weapon build other than vistani or tempest ranger) build.
They have to do power attack --> Cleave-> Great Cleave and Two Weapon Fighting -> Improved Two Weapon Fighting -> Greater Two Weapon Fighting -> Perfect Two Weapon Fighting. At this time they realize that the strikethrough changes to THF make it unbelievably better for play. They want to change the buiid to a THF.
They don't want to spend a money buying a lesser heart of Wood.
They have to have a bunch of Flawless Eberron Dragonshards and remove GTWF and fill it with a junk feat, wait three days, then remove ITWF fill it with a junk feat, wait three days, remove TWF and replace it with THF, wait three days, remove the junk feat used to replace ITWF and replace with ITHF, wait three days, remove the junk feat used to replace GTWF and replace with GTHF.
This would take 12 days, require 5 flawless shards.
More likely the person would retire the character, delete the character, stop playing the game and/ or delete the account.
It should be possible to just grab the THF feat and release all the prerequisite feats at the same time requiring the person to chose a new feat for theswe released feats at each of these levels before logging off, starting with the lowest level.
There are other situations where this cascading prerequisites cause all kinds of problems, but his was the most obvious to me.
