I don't understand ppl who says that complaining about arena problem is wrong, they can't fix it, instead giving some promises, how ppl should feel if everytime they hear "next week", "yeah problem solved, next week", "totally we solved problem, but for better game experience - next week"
And yes, you must also give people compensation on that bug: first cos this thing shouldnt happened ever, second february is shorter month, and you giving people even lees time to get six path rank next time.
