Change Legendary chance to pseudorandom

[Thunderstorm]

As Kaas stated above the Head Dev of this Mod is putting his IRL time into this mod and due some circumstances he doesnt have as much time at the moment

Kaas didnt say its not possible to change he just said it most likely wont change in the near future since the Head Dev doesnt have alot of time to review the new Requests and Kaas showing "a ton of requests which all require review" doesnt help in that situation.
