I get why MVPs were removed from spotlights, however, was it any worse than the current card drop event we have going on? I personally don't think so, and it's a safe assumption that other people agree. Please include them going forward.
Just don't run both spotlights and this type of event concurrently and it should be fine. Tao Gunka Cards flooded the server in the past due to a combination of spotlight, Tao being an option in MVP summoner (4h cooldown), a drop event, and spotlight not ending when it was supposed to, not due to the spotlight itself.
