Gollux

Oh yes its not a good argument because EVERYONE has friends with 50k+ ranges. Oh and you know everyone that's 140~150 should be able to kill a boss with 50mil or more hp.

Really? You know NOBODY with a 50k+ range? Guild members? Alliance members? I find that very hard to believe.

Why are you trying to kill Gollux at level 140/150? Is it your personal goal to go kill a boss with a couple of passives maxed, and 1 level in your main bossing skill (not to mention a lack of Hypers) at best? Why not try at a higher level, when you have more of your class's potential unlocked?

Range differs greatly between classes, but almost all classes have ~30k range buffed if they're geared decently (at least, for an unfunded person who knows how their way around the game, and abuses events). I have multiple classes who share tradeable equips and they all have at least a 30k range when self-buffed. If I invested in some decent weapons (I use 60% scrolled weapons for most of them, usually from Event Shops) and some cheap, untradeable gear (%stat Rings, shoulderpads, pendants maybe), their buffed ranges would rise to 50k easily.

The only two classes that I have invested into more than this are my Mercedes, who is sitting at a comfortable ~60k range buffed, and my Angelic Buster who sits at close to 500k buffed (I admit this is due to some frivolous spending and my absolute love for the class).

Lets make that class have low defense no guard skill or defense booster. [Good example; Kanna] Oh and lets add insult to injury by not making any pots work but have a cooldown.
Now does that sound fair to you? Cause it doesn't to me its just plain annoying.. Seriously unless you're funded or know people you're pretty screwed if you're poor. Especially if you're a class like Kanna, Hayato, Mage, or most archers(Because of their low hp not because of their range attacks) and mages I know Hayato is a warrior class, but he isn't like most warrior classes.

You can easily bypass the potion cooldown by leaving, using a potion and re-entering the room. The only reason you'd be blocked from leaving is if you let the mobs get to the middle, which shouldn't be hard since fighting in the middle of Gollux's jaw is one of the more efficient ways to take him down.

Avoiding Gollux's attacks isn't rocket science. Just stay in the middle (where the open portal is), and Teleport/Dankuusen/Ether Pulse/Double Jump/Glide Blast to the other side when Gollux readies his attack. Even the Explorer Warrior classes should have little problem with this ever since the introduction of Slipstream, unless you go brain-dead during the fight and cannot press a button in time.

As for the "poor" of Maple, it's entirely their fault that they're at that level where they cannot participate in ANYTHING. Why should they be rewarded with good equipment if they put zero effort into making/fusing equipment or merching? I agree that having an enormous part of the high-level experience blocked off by an equally enormous paywall is incredibly stupid, but the lower level modes of Gollux aren't blocked off by the paywall, they're inaccessible because the player is lazy and does not want to invest time into making decent equipment to take him down. Hell, I'm sure plenty of people got their Superior equips before Nexon removed the coin drops from the shoulders and abdomen.
