Multi-Person Adventuring... and the lag
With the introduction of Co-Ops, the legacy issue with adventure lag is becoming unbearable. It's no longer acceptable if you wish us to participate in adventures with other people.
Co-Ops, which force people to play together are lagging very badly. This bug has been around since the game was first released, applies to all multi-person adventures, and it has never been addressed because there was very little reason to do so. People would clear 95% of the adventure, 'tag' the other slots and do a final clear. But in a co-op, you have to deal with the lag from the get go.
My computer is not an issue, I run current games with little or no lag with max graphics. Please find a way to remedy this, or stop trying to encourage us to do them by putting the big event prizes solely on them.
