Well at least there are tokens now. Back in 1.0 era, when Ifrit was added, you had only a personnal chest with a chance to drop a random weapon. If you already had the weapon when one did drop you got nothing. back then I got 6 blm staff in a row in over a hundred runs while someone else from my LS got every single weapons in less runs. RNG do be like that sometimes.

Honestly I always felt like RNG is just lazy design to artificially extend game time. RNG for non-essential, bragging right stuff is one thing but gear should be available at the same pace for two people that put the same effort into it.
