@CSZ : Yeah, I had that as well, that’s why I tried it in normal difficulty. After it happened twice, I just had to switch back to normal to see if I was wrong, and it turns out I wasn’t. To be honest, I’ll stick to normal to play the Arena as long as it isn’t fixed.
Oh, and let me give you a tip. Change the difficulty before paying the Arena fee, close the game and restart it. When I didn’t do it, the Arena kept being on the same mode (Warlord, Hard or whatever difficulty I was on when I paid the fee). It’s a shame, but I hope it’ll get solved. I understand your pain, went through it earlier too, three times (I was changing the difficulty each time, from Warlord 3, then 1, then Hard, then back to Normal to check my theory). Lost the first one entirely (zero wins), and the two thereafter with only 3 and 4 wins respectively (although I did have pretty crappy line-ups too ).
