It's more like 150 weeks since every event gives you 2 Shards now. Also, if you're in a good Union, then you're going to get like 10+ extra Shards per month from UE, taking total time required down to... 7 months or so? And finally, in theory you can get a brick from Tower events, but realistically you won't until the second one (if I've understood how shit works right).
But yes, obviously the FLB stuff for Hime/Dragon Eye weapons are meant for massive whales only. The tiny trickle of "ooo free shiny is cool isn't it!!!!1" is utterly pathetic.There are?
Well, Awakenings, I guess. But since our Shard income is shooting through the roof and since you won't have all the Awakened Hime anyway (if you did, Dragon Eyes wouldn't be a problem for you)... well, practically speaking Dragon Eyes are not a bottleneck anymore. Or well, soon won't be. Give it a couple of months and everyone should have all of their Awakenable Hime Awakened. They've demolished the Gem barrier with infinite Gem Quests + Gem Gacha, the SSR book barrier starting from this event (Iluyanka) and the Dragon Eye barrier with Union Events.
