yes, bots would allow Auto fight to remain in WB, Also then it would create the Autofight in heroics and maybe auto combine for the people who are not vip5 in runes.
More complex games have them, so it would be simple to make a macro to do that here.

Most people who work are not able to sit infront of pc at 10am or 3pm and click for an hour.
So for these people to participate in WB they would need to move time zone, start over, cant see that happening.
