Firstly, People wanted a challenge, But noto went to Loki in a group of 15 and spent 3 hours hitting it.... That is not a challenge, that's just stupid.
Drop rates have never been higher? That's laughable. But then looking at your post where you say TDB, which may be a powerful spell would take a new player 40 hours of camping a boss that they cant kill to get says it all.
Mob count. You state in the event we spawned over 25k mobs ect ect.. Yet places continue to be pulled down? For one example Lakes, Was never a fast place to level, used to have what 500+ mobs? now that's around 280 on floor 2? why is this? This is exactly what I am talking about, This happens in ever area over time. Desert mines may as well have 2 floors, the floor naga champ spawns and the floor mount spawns. Then City 4f, As any other floor mobs are so spread that its just a waste of time hunting them unless you want to make 2% an hour.
Brings me back to gold. You say people must hunt to make gold....when was the last time you checked the price of a gold bar? now upto 50 gg some days. Is this because no-one hunts gold? Nope, this is because the only way to make gold, is to go farming flowers.
Look you can just see this as people moaning and wanting everything on a plate. or you can actually try and engage with people to make the server more fun and actually retain some player base.
