Returning player here.
When I fired up GoIO again I looked for 30minutes for the old game list, apparently all we have now is that huge "Play" button that puts you in some sort of queue. Chat was empty, there is no indication how many, if any, other people are online (well, I got response to my question about the lobby, so at least one other player was on) and it's now impossible to simply change role to get a game going (since you can't know what some match is missing) or pick a game based on "known faces" (from previous games), since, well no games to be seen.
I always found that watching the games in the lobby made the game feel "alive", sure the lobby had its problems but a huge chunk of them would have been solved (at least from a player point of view) by remembering the filters between games/sessions.
I also can't find any other information about this change, if there was any resistance to it then I can't find it, or maybe all regulars had already stopped playing PUGs anyway so they don't care or maybe this is actually awesome for most. But personally, as a returning casual player, I find this change to be really off putting, sorry.
