I would like to see VF remains flexible and allows work-life balance, therefore, i would like to suggest the devs to have flexible scheduled time to play conquest. I used to play Valkyrie Connect that guild vs guild runs for 12 hrs since guild master starts guild battle. Each player can attack in guild battle until all units are killed (they are on their own convenient time to do this). The guild battle will be over when we kill enemies to reach crystal and destroy it. If not, it will continue till time is up.
The devs may not have to have the same long period but i wish the devs design the conquest period per day to be long enough. Not restricting or forcing 35 players to get on at the same time within 1-2 hrs after conquest is started. This should give more flexibility to all players who have to work or study.
