For every map plot in the game, there may be several collection points, out of these, some will be spawning HaT / EDI. I am not sure if the spawned HaT / EDI are fixed and followed a certain pattern.
So what I am proposing is this:
For every map plot, maybe 1 or more of these spawned node will be made dedicated, in such that they will spawn a fixed schedule of HaT / EDI. For example,
Node 1 will follow this schedule, 7:05 am will spawn 8-Star Zinogre, 8:05 am will spawn 8-Star Deviljho, 9:05 am will spawn 8-Star Kushala, 10:05 am will spwan 8-Star Mizut, 11:05 am will go back to spwan 8-Star Zinogre, and so on.
Node 2 will follow this schedule, 7:30 am will spawn 8-Star Deviljho, 8:30 am will spawn 8-Star Kushala, 9:30 am will spwan 8-Star Mizut, 10:30 am will spawn 8-Star Zinogre, 11:30 am will go back to spwan 8-Star Deviljho, and so on.
The rest of the nodes in the map plot, can remained to spawn random HaT / EDI, such as 6-Star Monster to complete quest, event monster, etc.
If there is a need to increase the number of 8-Star Monster slot into the schedule, the interval between each spawn can be reduce to as such:
For Node 1, 7:05 am 8-Star Zinogre, 7:50 am 8-Star Deviljho, 8:30 am 8-Star Kushala, 9:05 am 8-Star Mizut, 9:50 am back to 8-Star Zinogre and so on.
I think in this way, there is more consistency and all players who are looking to farm a certain monster’s rarity 6 item to upgrade their gears, will be able to do it with more ease, instead of needing to be always on the look out for the HaT / EDI spawn.
I hope this can be clearer in my proposal, and if players who think this will greatly help them in their journey, they can cast a vote to support it, and hope the management will consider the implementation.
