I agree, the drop rate is too dang low... it took me like 2-3 hours to max it out (included DIPQ + Evo Lab + Kiritas/World Tree Dailies). Not to mention that the upgrade chances from getting A > S is 30% chance.Bud, the event just started. Give it a while. You get coins from the envelope things that appear over your head every now and then too.How does the event just starting have any impact on how low the drop rate is, and how many you need to max out? Better to bring it up now than later.
