Okay Rito here's my two cents' worth.
We want to know how you plan to make this champion viable for the masses.
I'm talking MASSES! The bazillion or so of us who pay a few bucks every time a new champ comes out, and then realize just how worthless he/she/it is without a team comp built around it. Or that they can't carry well when your support goes AFK. So you give us one that means GG when the support goes AFK?
Maybe make it so when Kalista dies she has to re-unite with her soul-bound, or something. You're the ones with lots of ideas. We know you can make it fun, we've seen you do some cool stuff before. Come through here- she needs a way to not instantly become worthless to bronze players who get AFKs in over 10% of all ranked games they play. Especially supports, because for some reason those who play support decide that lunch is more important than finishing.
We understand you don't care much about us weaklings. But I think that the reason people who play feel it's okay to just AFK is precisely because you've built the whole game to cater to people who play it for a living. We masses don't matter as much. And eventually we're going to quit, like the masses have on some other MOBAs that refused to listen to our complaints.
