Clearly never played a pc server if you'd rather trust an xbox server over a rental, all those youtube channels you watch, they all rent servers, nerd parade, slipg8r, jade plays games, H.O.D, nearly all of them host servers from rental services...
You dont have to rent one but the stability, frame rates, ping, ability to save, extra options and room for added players and server clusters is the reason to pay out for it. Xbox dedicated servers will be dead after august 8th.
