So, they run the event at 2am/8am/2pm/8pm, so everyone can attend one of them.
So, the EMs are having to be paid 4 times as much for running the same event 4 times.
Not to mention that you might only be able to attend one between work and sleep, whereas people who are able to take the day off work and mainline caffeine could attend all for, which would be SO UNFAIR
Still less unfair than cutting out players from a given EM Event because their real life schedule cannot be compatible.
Besides that ways can be found to prevent players to attend EM Events multiple times, even if that happened it would be less unfair than only have 1 Event schedule missed by many other players.
Why ?
Because "if" in an heavily item based game that EM Event provides items usefull for game play, than those players who have been unable to attend will have to purchase them from those other players who were more lucky to attend them.
Instead. if more EM Events are held at various times chances are that more players will eventually be able to attend them and get those items that can well improve game play on their own without having to spend sometimes hefty sums to buy them from other players.
Sure, some players will have extra ones but if most players will have gotten their own who cares ?
So, it is IMHO vastly more unfair to cut out players from being able to get items on their own because of the real life schedules, rather than letting some players get extra ones which will be hardly sellable since most players already got their own.....
