Yeah, it's a good idea to enable 3 SR daily quest when going to Revgacha, E-Gacha or when hunting Limited R's in the R-Gacha "mini-events". Still, i prefer to save my Revgacha tickets for later, when i'll have achance to get cool R's that i want while trying to get Lil Lilith (i doubt they'll remove her from Revgacha, since most of the players want her either because she is the main PPS mascot, has live screenshots from the movie as her level-up images, and has one of the biggest SEDs in the game).
For example, i really want to get Jami Takahashi, Mio Yuizumi, Kashisu Kokuto, Ami Kondo, UrehaTakagi & Ayuko Onizuka, some of which were in the previous Revgacha deck and now got removed.
