So, with how random the spawns are and the tight window players have to kill these enemies, I've witnessed a lot of, well, toxicity in regards to those that aren't the required level being blamed for unsuccessful attempts. There are some players that happen to be in a zone farming materials when the weather changes, so it's a case of being on the wrong block at the wrong time as people flood that specific block to attempt to kill these enemies, or you have actual trolls that come in contributing very little who just want to, well, be trolls.
I play on Ship 3, so I don't know how it is for other Ships, but there seems to be plenty of blocks available with little traffic. Maybe converting a few, 5-10 of these blocks designated for Gigantix hunting and allowing only level 20s to enter will help funnel those who want to engage in that content into those specific blocks would be a way to help deal with the situation? It will keep the other blocks open for those who are just going about their leveling experience, locking out the low level trolls, and giving these players designated block(s) to linger in, should they so choose, to wait for weather changes.
