NEW CHANGES:

Mei:
Damage Received: 120% to 140%
Movement Speed: 50% to 60%

Other Changes:
Made it so that every hero on Team 1 has default settings instead of sharing Team 2 settings. Ex: If you are Mei on Team 1 before this change then you would have had 50% Health, 140% Damage Received and 60% Movement Speed. But now you will have normal stats such as 100% Health, 100% Damage Received and 100% Movement Speed while on default settings.

On Workshop Settings everything except "1. Number of Players Required to Start" has the maxed increase from 10 to 20.

Added some stuff back that didn't make it last update due to size constraints.

Big Changes
-Added Max Ammo to the Wanderer Settings in the Workshop Settings.

Small Changes
-Added a TP area for Hammond's if they got stuck in some specific areas.
