The poster above me goes by "Nee", and is someone who ragequit Discord because I wouldn't change firewall to be easier for him like it is on rAthena. He doesn't know how to use the skill, doesn't understand even the basics of how to vertical firewall, and demanded that I personally change it for him despite experienced players offering to help him. Yes, people like him actually exist. He even sent me multiple PMs asking me to change it because he told the guy that he played with that he was good at it.
I refused out of basic integrity and was very professional with him. Here is a gallery of him throwing a tantrum and stomping his feet when he didn't get his way. I wouldn't take him seriously as he does not seem right in the head, but frankly I wish him well. This is about all you need to know about how childish he is.
Lulz. Hey J, post the video Sayvon linked 2 seconds after his post showing "how OP firewall is in the right hands". The one that you said didn't count as an example of how firewall should be working, despite being on iRO classic.

Compare this to the
silky smooth Travels experience, where nothing is wrong, and I just suck at firewall and don't know how to use it and am a rAthena baby, despite literally not even playing rAthena servers. Pretty good example of my previous post where I wrote any criticism is "dismissed with a scathing comment that anyone daring to question it was just some renewal/rAthena casual and had no idea what **true RO** was really like.", and another great ignoring of the fact that my experience is based on officials, not rA.
My "wanting to change Firewall to be easier like on rAthena", by the way, is my saying that it was broken and monsters shouldn't be skipping through it every single time, where I provided multiple videos of how it worked on iRO classic and even fished up other videos from 2007 era. Firewall was not the only, but one among many reasons I quit, when you're having to constantly fight with the janky laggy server just to do anything, and a deaf, indeed brickheaded admin that refuses to listen to any criticism that something isn't working correctly.
BTW, here's my PM history with you. Don't resort to making things up now.

Funnily enough, the exact same issue exists on KokoRO. At least he admits it though!

Speaking of which, you're awfully quiet about the KokoRO parts, J.
