Watching the 1v1 tournament at the ASE makes me ask...
Why can't we have Snowdown Showdown on the featured rotation? We'd get more variety in the rotation, especially since it's the only mode that isn't 5v5 or larger. It's exciting, short, simple, and also pretty varied and balanced, with ASE match winning champs including (but not limited to) Olaf, Varus, Rengar, Darius, Ryze and Quinn, with good performances from AD Orianna and Twitch.
Heck, we don't even need a full remake and relaunch of the mode, like Ascension or Definitely Not Dominion. Just give us the mode that was just used in ASE and I'll enjoy it.
