I have looked into this, the only thing i can think of is that since the max unit levels are auto applied this is making it seem like its super fast, well because they are max level. I will mess around with it a bit more, i will see about making it as a toggle in the menu as well. I did think about using a random int number for units, so that all of the unit levels would be randomized but I have not decided yet.
What would you all want to see? We can go as simple as randomizing unit levels, or a full blown custom setup where you can select what the levels are per character <- warning, this will be very time consuming to build LMAO.
Please let me know of any other features that you feel need fixed or added. I will do my best to implement them.
