the only RNG that actually infuriates me is getting cap dungeon gear. Atleast with pentamelding i can just easily get more materia and can expect it to succeed in a decent amount of time. With level cap dungeons (Baelsars Wall, the Burn, the Heroes Gauntlet, etc..) its miserable doing them for hours and hours and not getting any closer to your goal, since its complete RNG with no guaranteed drops like levelling dungeons. Yeah blue mage can help with the lower levels but that wont help you do heroes gauntlet for that TEA bis.
