Bring several different events at once. So, not 2 energy based events, but let's say raid boss, 10 crate event and fvf. After that has finished bring epic boss, 25 crate event and fltq/ltq at the same time. And throw a ltb at it during both time frames. Give the super active players an edge. No one is forced to take part in the events. Let everyone play as they like. I know there are a lot of players who don't like this idea, afraid of falling behind due to inactivity, so be it.
