Due to the risks of patching large files and getting a threading error (a Unity issue which still occasionally pops up) we decided that we bundle The Master's Toolkit, Launcher and the Essentials pack into one Installer. This seemed to also resolve a lot of confusion about how to install different components/order of components to users, and we reduced support requests on this topic close to zero. We understand that it is a fairly large download comparing to a single launcher, but being compressed and worked into one installer file, it is a lot faster process than letting the launcher download and install software/pack separately.
