The quests are the same type. No change.
You know that some (no matter which) event start. So you buy more blacksmith, you can delete some units and start trainig, you can stop motivate players and visiting taverns untill the event start. You can spend some fp to research but not unlock it.
Because in all events are quest to recruits unit, scout province, research, donate, complete production, motivate or polish, win batles, vists taverns.
If you do that, that only complete some production can be time barrier.
But if you have 20 production buildings (a lot balcksmith) you can start 8x 8h production, 8x 4h production and other will let incative to 5min or 15 min productin.
So if first come guest to complete 8 or 4 h production you have quest complete earlier.
In many events you can complete a lot quest at first day, because there are eazy quests like spend XY fp, get XY coins or suplies, visit XY taverns, motivate or polish 20 buildings and other eazy quest.
I do not have to know the quests before event start and I can prepare.
FoE is strategy game so events require some strategy to. And my strategy is be prepared for events. I'm not hardcore player I play for fun so I do not try how fast I can complete all quest but. After 5 days I have complete 25 quests that is 5 quest per day.
I'm working so I have short time to play at midday and some small time at evening.
I play on 3 worlds (include beta) and I haven't any problem to complete any event at all worlds.
And I translate quests anw news from here (beta) for guild members in my main world.
And I have personal life to. FoE is not my life. But I know how to play and how to make it easier.
