I disagree with speeding up the process, players are already getting insane amounts of event items and it seems like over the years that cost of event item continues to rise to match the returns players get. Lower levels and new players can barely participate in purchasing event items. One click? This game would explode if you tried to actuate 200 functions in 1 click, never mind the 200 notifications.
With that said, I think that for BB to make the explorers deploy like the generals that there would have to be a gem cost to do that. Money to code it and money to limit how many monkeys can use it.
