Gollux

it has legit rewards, and it can cater to MULTIPLE levels of funding.

While I agree the difficulty system is just fine, the pot cooldown and overall not being able to work when fighting a body part is annoying they need to fix that. As for the funding that is debatable considering the items that'd make the most profit can only be gotten by killing hard/hell mode. Hard mode is possible, but hell mode is impossible not only that but the 'well-funded' or 'Elite' maplers will NOT pay for the items when they can get them themselves by killing Gollux. So really the only good level of funding is selling the scrolls since Nexon f'cked up the shop and made all the items one-time only buys.

You basically missed the entire point of my post. My point was that's the way it should be. Players that are more powerful should have access to appropriately more powerful rewards from harder bosses. Hell mod is not "impossible", it's to more powerful players than you what hard mode is to you.

What I mean is: You shouldn't be making 5b per pendant/belt that you grab from easy gollux. If you're not strong enough to take on a level, you have to fund yourself via the lower levels to attempt to one day be able to take on that thing you first deemed impossible. When you finally get there, your rewards is making 5b from the pendant/belt that you loot. Do you get what I'm saying?

In my world, the scaling for prices for the difficulties is actually very, very good relative to what it takes to beat it. The rarity of the higher level equips also helps balance it out.

Also, you're completely wrong on rich players not buying anything. There are 2 equips that you can't get from killing gollux (you must farm). They have to either farm or buy it from people who do. I'm not even going to address your complaints about boss mechanics because you could make that same complaint about every other boss skill in the game.
