I remember Mrrp asking these questions in one of their posts a while ago, so I wanted to re-ask them here in case anything's changed :) (plus I've been wanting to start a discussion in the comments lately lol)
What was your first event that you played? On what version was it? Do you consistently play or skip events?
How many 4*s do you have?
If you had any 4* dupes, around how many were they?
Have you spent money? If so, around how much did you spend?
Out of the 4*s you have, how many were you pulling from their featured banner, and how many did you pull from that banner?
Out of the 4*s you have, how many are you happy with having?
Have you sparked a card? (I.E. using the gacha stickers to exchange for a card)
Do you remember the most number of pulls you've done for one banner?
I've put in my own answer as well, so I'll try compiling the responses if we get enough!
