I guess I don't see why having them on Weekends AND Wednesdays is bad thing. The Deferi stuff is more limited, time wise, than the 24hour STF window. It's totally conceivable for a player to do the STFs that award double chips, then while waiting for the cooldown head to Deferi for that content. Cycle and repeat.
I'm unclear as to why offering more "player beneficial content" windows are a bad thing.
how about just randomly alternating the dates and times of ALL events?
why does this have to be scheduled for one or two specific days in the week?
if you put somethinh on the same day in the same hour there will always be players who miss out.
for example i can't play Saturdays because that is car fixing day for me and my dad. Yet the Deferi GMT event is on saturday... so i need to play tuesday in the middle of the night to catch it at least once a week?
randomize times and dates and everybody will have a chance at some point.
