Question about upcoming servant and gacha

New year's has a GSSR. I'm gonna roll for Merlin cos I don't really care for Eresh.

Eresh won't be here until next year

As far as I know, paid gacha always gave guaranteed SSR. The free one never give SSR guarantee.
I will choose merlin, ofcourse

None.

First, Merlin is a cheatcode that i don't want to use for hard content and he will be extremely easy to find on support for farming purposes.

Second, none of the Buster servants that come at the end of the year surprises me from a gameplay perspective or for favoritism...King Hassan comes close though.

Third, i have close to 0 quartz after failing to get Gilgamesh (again) and i'm strict f2p. So even if i wanted King Hassan, i won't waste my money on this.

My next target is probably Poster Girl CE on GudaGuda rerun, that CE has too many strategic uses and maybe i can get an Okita there. After that i'm waiting for 2nd summer banner to, at least, NP2 the best summer servant ever.
