Most MMOs don't have a 3 month patch cycle either. Ravex was also pretty short lived due to how easy it was to get the tome weapon back on 3.0, you'd get the i180 law weapon, then you'd run ravex with the 180 weapon and upgrade to i190 while saving esoterics for your i200 upgrade which only took ~3 weeks to get back then.
Only ex primal that died faster than ravex was bismark as he was only required to unlock ravex for a short amount of time and only dropped i175 stuff.
Actually, if we're going to complain about gear dying, why not talk about bisex weapons? They literally died on arrival since law weapons were a joke to get.
