FTL Multiverse - Where are all the good weapons?

I've played like 20 runs over the past couple days after remembering this game exists and I haven't seen a single Burst 2/3, glaive, ion 2, its all just shitty mod weapons or 'anti hull' beams/lasers or god forbid those awful fire lasers that do 0 damage.

I am an RNG hater and nothing makes me more pissed off than after getting nothing for a whole run, a jacked 4 shield double burst 2 and double missile ship completely wrecks me

->INB4 "THERE IS NO RNG UR JUST BAD"

ive got all the engine upgrades im getting cloak im making sure i have redundancy and it just doesnt matter cuz no good weapons show up in shops like wtaf
