Guys, I noticed something... It`s true or only coincidence !? In 7.000+ league you have 6 tickets (one at 10 min. )... So if I keep 10+ keys (reward) I have 71,4% win rate, if I keep under 10 keys I have 85,7% win rate or 100% (7 arena tickets). The question is better to spend the keys immediate or to keep until 70+/75 max. ??? It`s only a coincidence ?
