first I need to say this is not a troll post because I know ppl wont approve the idea.
Instead of 24h or 36h, cut it down to 12h and halve the quest avaiable, like this ppl from LS from different timezone example US/EU/JP can do quest together because quest are always avaiable just not as many as 36h.
as for ppl in LS with different timezone mix, some of you much have counter the problem when member log while other member always do their quest and if they join they ll leech.
also it is easy for LS to do quest and play together also, if you like this idea, vote for it
