I logged in about 1.5 hours before maintenance... >.<
Yes it would be nice for them to put it in News ahead of time like other games (especially since it's not simply weekly maintenance like MWA for example).
Plus they did maintenance like 2 days ago when they activated this event, why couldn't they have just done this then too?
On the note of this apparent guaranteed 6*, I already got Black Baccara from my last 10+1 go-round (she is Slice) but this is tempting... 5000 Gold = $50. One 10+1 is roughly $30-$35 ($100 buys I think 136 FG?) and the chance of getting a 6* is .5% x 11 (I know that's not the ACTUAL calculation, more of a rough estimate because I don't feel like doing the real math atm lol) = 5.5% so going 1.5x that money for a GUARANTEED 6* isn't too bad a deal, considering the likelihood of getting a 6* normally is pretty low and even 5* isn't that great either. That said, it's still a clear cash grab and you do not in any way NEED a 6* to clear anything so it's more for waifu and MOAR POWER that you'd do spend on the deal than actual gameplay needs.
