If CVs don't show up after 28 players, I sometimes start the room without them. IT CAN BE DONE.
Its fun to play with CVs, it gives you a bigger battle with more variables, but if getting it means people have to wait more, I don't mind playing with just 28 players.
More games played, more exp/hour. People should start exploring other type of battles besides 20/6/120... and that is entirely up to the hosts.
Shared Exp might be a little less of course, but players who improve their skills won't be needing it.
I feel the Key for faster games, are hosts determined to use the options available. SDE have made moves and given options, its people who have to use them.
Sometimes when I feel like it, I only play GBs with 28 people... in 2 minutes we are up and running. Think about it.
