Overhaul suggestion for BoS events

Had this idea for a while but thought it's time to pitch it out BoS events are every 2-3 months so it's a simple change but I think it would be popular have the BoS event run for the full month parallel to the mega event but keep the challenges for it then players are under less of a time crunch to get what the talismans/charcter is and it gives newer players a better chance to compete in them also one other ISSUE bring back sacrifice event challenges it lasts the full month so give us challenges that reflect a month long sacrifice event not just here's 2 new characters a month long CLAN challenge could be sacrifice 3 million essence I mean this is just a few ideas that rattled around my head so call it the ramblings of a madman but thoughts are always appreciated
