A master server provides an always-available sever to the game for general running needs, such as registering hosts. It does NOT do everything, especially provide power.
I remember you 3 and a half years back, I didn't know you still played you might not remeber me but i joined your game and asked how to make custome servers you replyed and said "No" -tichead. and i thought you were calling me tichead. lol ahahhaha ile never forget that.
