I'm not sure if this is the intended behaviour but either way it definitely needs to be communicated better. Each upsurge weapon has a "account limit 0/1", but once the player buys 1 of them, all of the weapon types gets locked out. I feel like a child that's asked to pick an ice cream flavour and watch in horror as all the other flavours but the one i picked get smashed into the floor after i get a scoop of the flavour i picked out carefully handed to me, that's what buying one upsurge razor and having the entire upsurge shop blocked out feels like. If this behaviour is intended, it should be clarified in the purchase limit "upsurge weapon shared purchase account limit 0/1" or something instead of just an "account limit 0/1" on each weapon.
