Its just boring 
I played for some time and pretty much 100% both seas aside from like 1 or 2 quests that are fishing. There is little to do once you have done everything
It’s boring yet the development tries to make it less boring by… throwing content at the wall and it just not sticking, except instead of realizing it isn’t sticking they’ll just keep throwing.
I’d say it sticks for a bit and then falls off, dragons update got be back to playing for the longest period ever since empires update came out
Sticks for a bit is still rather bad when the time between any update is multiple months at this point.
At this point its just how the roblox games are. Sudden activity and money spike whenever something new comes out.
It’s 99% the developer’s fault
