Increasing/Decreasing Arena Difficulty - Need helpful explanation
I've noticed difficulty in versus increases for about 15-20 fights and then gets more manageable, but it's not always consistent (sometimes it takes more battles for the difficulty to drop off, sometimes fewer).
I've had some good 50+ streaks, usually with evenly matched teams after passing the threshold, only to lose it to a team about five time stronger than my own (this happened when putting a team of of 4*s that weren't leveled up much).
Does anyone understand how exactly this works? At what point do your matchups stop getting more difficult (15/20/25 3 vs. 3 wins)? What causes a matchup during a long streak (like 50-100) to suddenly be extremely difficult (like a team ranked 3,500 matched up against a team ranked 25,000)?
