Since I'm an old player of dota (the former dota1 and currently dota2) I just may want to have my opinion considered on dota2 community for better.

I am currently asking for a gamemode perhaps to introduce further changes and might be tested by players before it become official as a patch since changes on 7.20 suprised many players.
As dota2 is always open to changes and it's a very good perspective that keeps it from getting into a dead game, so what I'm simply asking is an official gamemode if it is possible that respect players opinions and have a voting system for future changes in gameplay which players can play predicted ability or hero changes, get fimiliar with these changes before it gets official and then vote for changes ...
