Yes, Arena is rigged
I have found out from Googling many sources that the Arena algorithm is rigged. It is based on your player level and your total power rating, but your player power rating has NO bearing on the best team you can field in Arena or Tag Arena. I am at level 59 with a player power rating of 1.5M, but the highest power team I can put in Arena is only 150K power rating. Yet, I can only beat teams of less than 70K power rating. My fastest team menber has a Speed of 205 and the leader has a aura skill of increasing Speed in Arena battle by 32%, and yet I only get to attack first 1 out of 10 battles. I am at Silver 4 level in classic arena and I have to check every 15 minutes to refresh the list to to see if there is maybe 1 team out of the 10 that I have a chance in hell of beating. I have spent too much money on this game just to be held back by the stupid arena system. It is too out of alignment. And tag arena is no better. Explain how a level 50 24K rare champion can beat a team of legendaries all level 60, 6 purple stars, most with legendary artifacts at level 16 with 5 to 6 stars, and a power rating of 151K? If that is the case then I give up. It is useless to try for legendary champions and artifacts. The game in arena is way too unbalanced. Plus, my player power rating is a complete joke. It is only that high because I have around 100 rares that I keep around for trying different combos in faction wars. I don't have enough legendary and/or epic champions to field complete teams in faction wars. I have been playing for 130 days and spent hundreds of dollars on offers in the shop since this game is "realistically" pay to play. There is no way to get this far without paying. Before you ask I only have levels 10, 11, and 12 campaign missions left on nightmare, I beat the minotaur on level 15, all the potions keeps on 15 or 16, all the boos dungeons up to level 16 except spider's den, and I can make it to floor 50 in doom tower. Since the Hydra is so new I have not figured that out, yet. As for the missions I have only been able to complete the first 2 parts, but cannot get farther because I need to update ratings in the great hall, but can't do that because I would have to spend 18 to 20 hours a day trying to get 10 wins in arena battles. Like I said it is totally and completly unbalanced.
