Restored old skills and trees before the Update 100.
Tier Bonuses and Prerequisites has not been added yet, but I will try to return it someday.

WARNING:
All your skill sets will be reset.
You can only play with people who have this mod.

Note:
"Pistol Messiah" being replaced by regular "Messiah" until ill find out the solution how to get it back without issues.
Those people who have a mouse with more than 3 buttons can refund skills without a dialog box using the [MOUSE 4], like "Fast Invest" button.

Special Credits:
TdlQ - for piece of localization code (The best one in my opinion).
Solo Queue Pixy - for the background recovery mod that I included in the code (Old skills are not the old skills without backgrounds).
My apologies if I should have to ask the authors first before taking them into the mod.
