This is in my opinion the best server there is for pre renewal ragnarok, extremely friendly community, GM's always around and easy to reach in game and on discord. Server has perfect balance between custom and vanilla content, there is plenty of custom gears/mobs/maps/events etc, but at the same time, it's not like custom things are OP, it feels like a proper, developed pre-re ragnarok. I've played ragnarok on and off for 10 years, and I ALWAYS come back to HeRO, for content and atmoshpere.
