I slightly disagree when portals become rare or open for a long time, especially if Rahab's portal rarely opens. why? because the elite zodias 4 mobs are very thick and hard to kill, even people who are full kraken can still be killed instantly by mobs / mini bosses, zodias 4 is not a good farming place for farm gold but a farming place for death. so if you really want the portal to open longer, then the mobs and mini bosses in Zodias 4 must be nerfed.
