But the bottom line is that you get the best probability of gaining 5* tanks by taking the most chances you can. That's not done with four factory slots plus once every month or so when you have enough cores to spend at the store. When I opened the fifth slot I increased the number of chances I can take by 25%.

On a totally different topic, is anyone else having trouble getting the new event mission to start?
