Question for arena grinders
Hey guys. So my worst arena because of how boring it is to get all the milestones is the summoner trials. My plan to finish it as fast as possible is to have as many rank 5 4 stars as I can. How many do you think I need to be able to go through 2 hours and when i finish those two hours, my top champs will be refreshed? So far I've got 97 rank 5s and i still need to wait 40 minutes for them to refresh.
