I've just spent over 45 minutes waiting in the ranked queue of the Arena without any opponents. I'm at my patience's end. How can I rank up if I can't fight anyone? Why did Oasis remove the feature of getting a random match after a certain time limit?

I'd suggest putting that feature back in, but I'm sure the people on the lower end of the ladder would complain about getting nothing but Super Kage opponents or some such. Nevermind that the Arena is already flawed by design with it's excessive reliance on overall Initiative.

I'd much prefer they keep ALL stats, including Initiative, at the base level without bonuses from equipment, runes, refines or charms or whatever. Perhaps a system of Rock-Paper-Scissors could be implemented to choose who gets bonus Initiative at Round 1? And then on Round 2 the other player gets bonus Initiative? It would certainly make matches somewhat fairer, though more reliant on luck.
