I don't see why people are actually whining soo much about backpeddling. If you played the matches on the given arenas on the NWML servers there is little room to actually backpeddle and spam like certain noobs do. Even if the person is backpeddling alot he can only go around in circles, making it alot easier to get in range of the enemy backpeddling. Even if that backpeddler gets certain advantage doing it, it's not like he can continue that for 1 straight minute like on an open field. I've only played 4 people but from what I can see, playing on the given arenas really do force you to get up close with your enemy and stop you from using "backpeddling" tactics, or at least abuse it to the extreme.
But either way I don't know why kids in league A are crying over losing some duels, what else did you expect joining the best duel league? Everyone there are more or less tryhards and actually good players, others may be some lost kid like those who've rage quit and didn't know what they signed up for. Either way it's just amusing to see people crying and arguing over this with fallible arguments when they should've known better.
