The real problem with arena is not the buffed defense or matching system, but the bots. If the bits were removed, players would rise and fall to where they belong. Currently the bots serve as a way for those with runes to rise much higher than they should. When players in crystal tiers are finding BPA in the 5000s, but silver tier is 6.5k and above, there is a problem. Get rid of all bots, let us face each other only.
