I'm not really certain why I hear many speak of being #1 in the Arena battles when the rewards vs. risks are not in your favor.
First off, you get 700 points for holding a position between 101-200 so why put a target on your head and go for say the 6-10 position for only 100 credits more. I feel it's better to play the background, reach the 101-200 Tier and hold there until you have a 7* team at minimum.
I feel too many are in a rush to be top dog and all it will do is cost you points when people remember you and attack you, not to mention the extra crystals you'll spend daily defending position. Our rewards are only based upon the end of day result, not how many times we need to play. Food for thought.....
