not more gem lot... f2p here
if miss this boat, when is next one
In my langrisser lifetime, I spent on 3 banners:
Listell/Lanford (Totally regretted. Listell became easier to get later, but its unknown to me at that time)
Yulia/Omega (Biggest spending. Got 5 Omegas before Yulia appeared)
Deedlit/Ashram (Least spending among the 3, since I saved up beforehand)
Yulia will not appear in any focus banner for a long time, but she will appear in another double SSR banner. (with shelfaniel if memories served me right) Its not a focus banner and she is not guaranteed.
As for omega, he will appear in some banners quite quickly, both focus and double ssr.
PS:
I am not sure which returning character/focus banners you will be interested in, but for the next 3+ mths, you probably won't be pulling much on the new char banners.
Betty/Rainforce: Don't waste time and resources on this. Both are not good.
Young Jessica/Emilia: Young Jessica is good, but not a must-have. Emilia is more for those without Ledin. She is inferior to Ledin though.
Yu Yu Hakosho: Only Yusuke is good, but not a must-have also. I have Yusuke and Hiei. Built up both and I used Yusuke quite often. Hiei up to now I haven't see him of any use except arena (even arena he is seldom used and not top tier). As for the rest of the 2 (Kurama and Toguro brothers), I never see people use them in pve and pvp contents.
Virash/Mystery Knight: Both not really very useful, but Mystery Knight do fill some niche.
So, if you can still get gems/tickets from story, time rift or uncompleted gate of fates, this is the banner you should do them for.
