To call the short 4 or 6 hour or whatever it is incursion timer obnoxious would be a generous understatement. You have a daily reset system - USE IT. One incursion per day, in a random zone, lasting the entire span of the day until the daily quest reset. Since you’ve finaly condescended to fix the incursion/invasion quests supressing zone quests while active, there is no reason whatsoever not to have this in place.
Don’t merely play monkey see monkey do in carrying forward broken Legion designs without alteration - do your heckin’ jobs and improve on them. I have yet to see ONE Legion design that’s been carried over that not only has not been improved on but is objectively worse than its predecessor.
