Reset all the level as soon as i was able to, last two levels i was struggling to get the skillblooms/dressblooms, was considering going for the last two Ampys, but in the end i did not bother because I realised there was still so much crap i did not want to draw. This was really hard, ie had to draw 30+ times on average before i could reset.
Overall this event was not enjoyable for me, it was more a chore to get all the drops and even being able to farm the ?-4 and ?-8 events and the SG missions that drop, was struggling to get enough Ancient coins.
I like how they tried some thing different for events, maybe in future they could make it more enjoyable.
I biggest dislikes were the following
Not knowing what the future contents of the Event Gacha are, only found out the next reset after resetting, let alone knowing the entire draws.
Same thing with the cost, you were told cost would increase, but not knowing what the cost per future draw were made planning suck.
the contents of the higher cost draws should have been better rewards, 100 normal gacha seeds OR one 3* knight for one 280 coin draw was well SHIT! and there was 18 / 50 chances of those, really not worth drawing that for the effort to get 280 coins.
Once again trying something different was appreciated, but i hope they know that sometimes new idea are not always going to be great ideas and there is room for improvement.
