EBFScorpiouprisingImplementing an entirely new, untested pick/ban system? Holy shit. Those playtests are going to be HELL. Getting 18 people into a mumble, looking through a list of 200 items and making choices about what to use, what to ban, remembering what items are available/unavailable, who picked what, whose turn it is to pick. ETC ETC.1) Pick/ban is not completely new; it already exists in Dota. Yes, it's not exactly the same, but the general architecture already exists.
2) Mumble is most certainly not going to be involved in an official Valve lobby option.
Subsequently, the selection system is probably going to be much simpler than "everyone has to unanimously agree on all the choices."
3) Your example of testing a new map is not exactly the same. If Valve wanted to test a map, they could simply roll it out to all the players by adding it to the official map list.
An enormous amount of data would be gathered even if few people play the map because it sucks (which in itself is data!) without any sort of manual effort on the map tester's part.
This last part is precisely what Valve is trying to do with an official pick/ban system: collect a vast amount of data from the large and diverse player base.
1) Yes the general architecture exists, for a completely different game with completely different set of balancing mechanics. I already referenced DOTA 2 and TF2 weapon bans in another post.
2) Valve asked us to come up with a pick/ban system in a week through playtesting in pugs and scrims. Of course we are going to use mumble to implement that, unless some crazy wizard comes up with an IRC script in two days. Whatever system they end up using, we would have to construct it from the ground up. Of course the ingame system would be easier, but we have to come up with the system first before they put it into the game.
3) Who is talking about Valve testing a map? I'm talking about me and comp players testing a map, and highlander players playtesting the pick/ban system. Valve asked us to playtest and figure out something that works, they aren't just going to magically give us something to use.
4) Valve can't collect data from a pick/ban system if no pick/ban system exists!
