The droprate on mirror just makes it totally useless. 1 in 40 divided by 8 people is simply a joke. Oh wait, you with 8 people from your fc? Then why the hell arent you working on t7 instead over wasting time in levi hoping to get a miniscule chance of a droprate. Theres even a i100 weapon that you can get from doing under CT gear required dungeons using the damn party finder. I dont get the fc's that are wasting all this time on that silly mirror even though i personally want it really bad. Just to have a couple different, totally useless, secondary stats? Not gonna drag my fc through there, i'll just use the shitty relic animus and get more coil tries in.
Bad design SE. I know you need to have the time required to get levi weap to be about the same as a coil weap or animus, but due to the absurd RNG factor it is just a massive waste of time comparatively, to not even mention trying to get your levi mirror solo by joining a pf.
