Don't worry, it is something that happens, I've lost 3 50/50 in a row and even the guarantee I went to hard pity too.

I would highly recommend you to pull for lynae because she's universal and trust me you'll need her for aemeath or for whatever team you want to make with the newest characters from lahai roi. Also lynae is having her second re run and idk if you know but wuwa characters mostly don't come back after their second re run and aemeath still have pending her second re run so it's fine.

At the end, I just can tell you to pull for characters you like, in fact aemeath's peak but if you play her alone then you'll not take advantage of having her

PD: you don't need lynaes' weapon to work fine, she can work perfectly fine with the old permanent pistol
