i will do that from now on as well. I have really a hate relationship with 5*+ tickets. In all this years playing (on and off) since 2016, i got two 6* from these i think.
2018 Tall Stewartia Christmas and now this year Meconopsis (Swimsuit).
I always roll my Salt Tickets right away but maybe i should stock up on them and roll them at the End of the Year like you do. I wanted to do a pact at the End of this Year anyway.
I have really looked through this Thread and searched through all Screenshots i did over the cause of many years and it turned out most luck i have is in late Autumn, Winter and Spring till April. After that and for most if not all of the Summer my Luck takes a deep Nose Dive.
Sometimes i just want to roll Salt Tickets if i can't roll the Regular Gachas to save up for specific Units.
These dry phases only doing dailys are a bit monotone...That's one of the reasons these Special Occasion Gachas like former Golden Weeks the last couple of years are nice. To get a bit more Action going
