So back to why Pathfailure is an abomination.
I've covered a few reasons already, but because it amuses me...
The Magus.
In short:
Paizils release a shitty version of the Duskblade, who lacks just about everything a Duskblade needs to be a viable Duskblade. Paizils attempt to defend their fail class. Smart people point out it's completely full of fail, and to return to the drawing board to start from scratch.
They take a diversion to mess with something that makes casters take long amounts of time to resolve their turn in combat, after complaining melees aren't allowed to have nice things if it slows down their turn.
Then they come back to it... and it still sucks. In most of the same ways even. Except now it also has a shitty GMW a few times a day, and some other minor things you could completely forget to write down and it would make no practical difference.
This is an example of what you get when "lots of features, even if they suck" is your design goal. Shiny useless stuff to distract the mouth breathing fuckwits, no actual substance to stop the monsters from slaughtering said mouth breathing fuckwits, but that's ok. Because like 4.Fail, most of the people that claim to be playing it are not actually playing it. They are instead playing Magical Tea Party and calling it 4.Fail/Pathfailure.
